Additional Arithmetic Rules: Using multiple rules

To solve this problem, we'll follow these steps:

• Step 1: Evaluate the expression inside the parentheses, focusing first on multiplication.
• Step 2: Perform the division inside the parentheses.
• Step 3: Simplify the expression by completing the subtraction inside the parentheses.
• Step 4: Subtract the result from 35.

Now, let's work through each step:

Step 1: Evaluate the multiplication inside the parentheses.
The expression is $3 \cdot 2$, which equals $6$.

Step 2: Perform the division inside the parentheses.
Substitute the result into $39 : 6$, which is $39 \div 6 = 6.5$.

Step 3: Simplify the expression inside the parentheses by performing the subtraction.
The expression becomes $82 - 6.5 = 75.5$.

Step 4: Subtract the result from 35.
Hence, $35 - 75.5 = -40.5$.

Therefore, the solution to the problem is $-40.5$, which corresponds to the first choice given in the possible answers as $-40\frac{1}{2}$.

To solve this problem, we'll follow these steps:

• Step 1: Evaluate the expression inside the first parentheses, $(38-92)$.
• Step 2: Evaluate the expression inside the second parentheses, $(56+33)$.
• Step 3: Substitute these results back into the main expression and simplify.

Now, let's work through each step:

Step 1: Calculate $38 - 92$.
This results in $-54$.

Step 2: Calculate $56 + 33$.
This equals $89$.

Step 3: Substitute these values into the original expression:
$124 - (-54) - 89$.

• First, simplify $124 - (-54)$.
  Subtracting a negative is equivalent to adding its positive, so this becomes:
  $124 + 54 = 178$.
• Next, subtract 89:
  $178 - 89 = 89$.

Therefore, the solution to the problem is $89$.

To solve the problem $78-(39-47)-(95+3:\frac{3}{5})$, follow these steps:

• Step 1: First, evaluate the expression within the first parentheses: $39-47 = -8$. Thus, the expression becomes $78 - (-8) - (95 + 3:\frac{3}{5})$.
• Step 2: Simplifying $78 - (-8)$ gives $78 + 8 = 86$. The expression is now $86 - (95 + 3:\frac{3}{5})$.
• Step 3: Calculate the division within the second parentheses $3:\frac{3}{5}$ by multiplying 3 by the reciprocal of $\frac{3}{5}$, resulting in $3 \times \frac{5}{3} = 5$. Thus, $95 + 5 = 100$.
• Step 4: Substitute back into the problem, yielding $86 - 100$, which equals $-14$.

Thus, the solution to the problem is $-14$.

To solve this problem, we'll follow these steps:

• Step 1: Simplify the nested expressions and handle the negative signs.

• Step 2: Perform the division operation involving the fraction.

• Step 3: Combine the results from the two operations.

Now, let's work through each step:

Step 1: Address the nested subtraction.

First, simplify the innermost expression: $-94 - (-32)$.

Recall that subtracting a negative is equivalent to addition: $-94 - (-32) = -94 + 32 = -62$.

Now substitute this result back into the main expression: $-55 - (-62)$.

Again, subtracting a negative is addition: $-55 - (-62) = -55 + 62 = 7$.

Step 2: Resolve the division by a fraction.

Calculate $12 \div \frac{3}{4}$:

Dividing by a fraction is equivalent to multiplying by its reciprocal: $12 \times \frac{4}{3} = \frac{48}{3} = 16$.

Step 3: Combine results.

Now we add the results from steps 1 and 2: $7 + 16 = 23$.

Therefore, the solution to the problem is $23$.

To solve the given expression $130 : \frac{10}{2x} - (23x - 204)$, follow these steps:

• Firstly, simplify the fraction $\frac{10}{2x}$ to get $\frac{5}{x}$.
• Next, perform the division $130 \div \frac{5}{x}$. This is equivalent to multiplying $130$ by the reciprocal, resulting in $130 \times \frac{x}{5}$. Simplify this to get $26x$.
• The expression now becomes $26x - (23x - 204)$.
• Distribute the negative sign inside the parentheses to get $26x - 23x + 204$.
• Simplify by combining like terms, which yields $3x + 204$.

Therefore, the solution to the problem is $3x + 204$. This matches option 1 from our choices, confirming it as the correct answer.

To solve the problem $300:(20\cdot8)-(13+200)$, follow these steps:

• Step 1: Evaluate the multiplication $20 \cdot 8$.
  $20 \cdot 8 = 160$
• Step 2: Perform the division $300:160$.
  $300 \div 160 = 1.875$
• Step 3: Calculate the addition inside the parentheses $13 + 200$.
  $13 + 200 = 213$
• Step 4: Subtract the result of the addition from the division.
  $1.875 - 213 = -211.125$
• Step 5: Convert the decimal to a fraction, if necessary.
  Since $-211.125$ is equivalent to $-211\frac{1}{8}$.

Therefore, the solution to the problem is $-211\frac{1}{8}$, which corresponds to choice 3.

To solve this problem, we'll follow these steps:

• Step 1: Calculate the expression inside the parentheses by performing the division $210:15$.
• Step 2: Add the numbers inside the other parentheses, $12 + 42$.
• Step 3: Use the result from Step 1 to perform the division $28:\text{(result of Step 1)}$.
• Step 4: Subtract the result of Step 2 from the result of Step 3.

Now, let's work through each step:
Step 1: Compute $210 : 15 = 14$.
Step 2: Compute $12 + 42 = 54$.
Step 3: Compute the division $28 : 14 = 2$.
Step 4: Finally, compute the subtraction $2 - 54 = -52$.

Therefore, the solution to the problem is $-52$.

To solve this problem, we'll follow these steps:

• Step 1: Simplify each division separately.
• Step 2: Combine the results.

Now, let's work through each step:

Step 1: Simplify $39 : (x \cdot 3)$.

This is equivalent to $\frac{39}{x \cdot 3} = \frac{39}{3x}$.

Step 2: Simplify $\frac{y}{x} : \frac{y}{4}$.

This is equivalent to $\frac{y}{x} \times \frac{4}{y} = \frac{4y}{xy} = \frac{4}{x}$.

Step 3: Add the results from Steps 1 and 2.

We have:

$\frac{39}{3x} + \frac{4}{x}$

Simplifying further, find a common denominator for the fractions, which is $3x$:

$\frac{39}{3x} + \frac{4 \cdot 3}{3x} = \frac{39 + 12}{3x} = \frac{51}{3x} = \frac{17}{x}$.

Therefore, the solution to the problem is $\frac{17}{x}$.

To solve this problem, we'll follow these steps:

• Step 1: Evaluate the division $400 : \frac{20}{13}$.
• Step 2: Subtract 12 from the result obtained in Step 1.
• Step 3: Subtract the entire result from 35.

Now, let's work through each step:
Step 1: Evaluate the division $400 : \frac{20}{13}$. Division by a fraction is the same as multiplying by its reciprocal, so we have:
$400 \times \frac{13}{20} = \frac{400 \times 13}{20} = \frac{5200}{20} = 260$

Step 2: Now subtract 12 from 260:
$260 - 12 = 248$

Step 3: Finally, subtract the result from 35:
$35 - 248 = -213$

Thus, the solution to the problem is $-213$.

To solve this problem, we'll follow these steps:

• Step 1: Solve the division inside the parentheses: $7 : \frac{2}{26}$ is equivalent to $7 \times \frac{26}{2}$.
• Step 2: Calculate $\frac{26}{2} = 13$.
• Step 3: Thus, $7 \times 13 = 91$.
• Step 4: Determine the full product expression: $4 \cdot 13 \cdot 91$.
• Step 5: $4 \cdot 13 = 52$.
• Step 6: Therefore, $52 \cdot 91 = 4732$.
• Step 7: Compute the second product: $13 \cdot 13 \cdot 7 \cdot 4$.
• Step 8: Begin with $13 \cdot 13 = 169$.
• Step 9: Continue with $169 \cdot 7 = 1183$.
• Step 10: Finally, $1183 \cdot 4 = 4732$.
• Step 11: Subtract the two calculated products: $4732 - 4732 = 0$.
• Step 12: Subtract this result from 1, yielding $1 - 0 = 1$.

Therefore, the solution to the problem is $1$.

To solve this problem, we begin by simplifying the expression inside the parentheses: $y \cdot z + 3z : \frac{z}{x}$.

First, evaluate the division: $\frac{3z}{\frac{z}{x}}$. This can be simplified by multiplying by the reciprocal, yielding $3z \cdot \frac{x}{z} = 3x$.

The expression inside the parentheses becomes $y \cdot z + 3x$.

Now substitute this back into the entire expression: $3x - (y \cdot z + 3x)$.

Apply the distributive property to the negative sign, resulting in: $3x - y \cdot z - 3x$.

Combine like terms: $3x - 3x - y \cdot z$ simplifies to $- y \cdot z$.

Thus, the solution to the given expression is $-yz$.

Let's solve the expression $48:\frac{10}{x}-(x+5)$.

Step 1: Change the division to multiplication by the reciprocal.

We have $48:\frac{10}{x} = 48 \times \frac{x}{10}$.

Simplifying this, we obtain:

$48 \times \frac{x}{10} = \frac{48x}{10} = 4.8x$.

Step 2: Incorporate the subtraction operation.

We now have $4.8x - (x + 5)$.

Distribute the negative sign:

This gives us $4.8x - x - 5$.

Step 3: Combine like terms.

Simplifying further, we have:

$4.8x - x = 3.8x$.

Thus, we end with:

$3.8x - 5$.

Therefore, the solution to the problem is $3.8x - 5$.

Upon reviewing the given choices, choice 1 corresponds to our calculated result: $3.8x - 5$.

To solve this problem, we'll follow these steps according to the order of operations:

• Step 1: Simplify the expression $35:(7 \cdot 5)-(2+9:\frac{3}{2})$.
• Step 2: Calculate $7 \cdot 5$ and $9:\frac{3}{2}$.
• Step 3: Simplify the division $35:35$ as well as $9:\frac{3}{2}$.
• Step 4: Evaluate the expression step-by-step.

Now, let's solve the expression:

Step 1: Calculate the multiplication: $7 \cdot 5 = 35$.

Step 2: Calculate the division: $9:\frac{3}{2} = 9 \times \frac{2}{3} = 6$. We use the reciprocal of $\frac{3}{2}$.

Step 3: Substitute back into the original expression: $35:35 - (2 + 6) = 35:35 - 8$.

Step 4: Simplify the division: $35:35 = 1$.

Step 5: Calculate the subtraction: $1 - 8 = -7$.

Therefore, the solution to the problem is $-7$.

To solve this problem, let's simplify the expression $79 - (35 - (-9)) - (10 + 43)$:

First, evaluate the expression inside the first parentheses:

• $35 - (-9)$ is equivalent to $35 + 9$ (since subtracting a negative number is equivalent to adding its positive counterpart).
  Thus, we have $35 + 9 = 44$.

Second, evaluate the expression inside the second parentheses:

• $10 + 43 = 53$.

Now substitute these values back into the original expression:

• $79 - 44 - 53$.

Finally, perform the subtraction sequentially:

• Calculate $79 - 44 = 35$.
• Then, calculate $35 - 53 = -18$.

Therefore, the solution to the expression is $-18$.

Checking against the given choices, the correct choice is:

• Choice 2: $18-$ corresponds to $-18$.

To solve the expression $84:(2\cdot7)-(63-2x)$, we shall simplify step-by-step as follows:

• Firstly, simplify the division: $84 \div (2 \cdot 7)$.
  • Calculate $2 \cdot 7 = 14$.
  • Then, perform the division: $84 \div 14 = 6$.
• Now, substitute the value from the division back into the main expression: $6 - (63 - 2x)$.
• Simplify the expression inside the parentheses: $63 - 2x$.
• Finally, apply the subtraction:
  • Distribute the negative sign: $6 - 63 + 2x$.
  • Combine the constant terms: $-57 + 2x$.

Therefore, the expression simplifies to $2x - 57$.

To solve this problem, we will simplify the given expression step by step:

First, consider the expression inside the innermost parentheses: $(\text{-}14)-(-7)$.

Using the rule that subtracting a negative number is equivalent to adding its positive counterpart, we have:

$(\text{-}14)-(-7) = \text{-}14 + 7$.

Simplifying this gives us $-7$.

Now substitute back into the original expression:

$-38 - (-7) - 3(7 + 4b)$.

We can handle the next operation as follows:

$-38 - (-7)$ is equivalent to $-38 + 7$.

Simplifying this gives us: $-31$.

Next, consider the term $-3(7 + 4b)$. Using the distributive property, distribute $-3$:

$-3 \times 7 = -21$.

$-3 \times 4b = -12b$.

Thus, $-3(7 + 4b) = -21 - 12b$.

Substitute back into the expression:

$-31 - 21 - 12b$.

Combine the constants:

$-31 - 21 = -52$.

The simplified expression is:

$-52 - 12b$.

Therefore, the solution to the problem is $-52 - 12b$.

To solve this problem, we'll follow these steps:

• Step 1: Simplify the expression within the division $9a:(5a\cdot3)$.
• Step 2: Simplify the expression by performing the arithmetic operations.

Let's solve the problem step by step:
**Step 1**: Simplify $9a:(5a\cdot3)$.
First, compute the product in the denominator: $5a \cdot 3 = 15a$.
Now, perform the division: $9a \div 15a = \frac{9a}{15a} = \frac{9}{15} = \frac{3}{5}$, assuming $a \neq 0$.

**Step 2**: Substitute back into the original expression:
The expression becomes $49 + 2a - (54a + \frac{3}{5})$.
Now distribute the negative sign: $49 + 2a - 54a - \frac{3}{5}$ Combine like terms: $(49 - \frac{3}{5}) + (2a - 54a)$ Simplify: $48\frac{2}{5} - 52a$

Therefore, the solution to the problem is $48\frac{2}{5}-52a$.

To solve this problem, we'll simplify the expression $17-(215-(314+95))$ step-by-step:

• Step 2: Substitute back into the expression. We now have $17-(215-409)$.
• Step 3: Simplify the subtraction inside the parentheses. Compute $215 - 409 = -194$.
• Step 4: Substitute back into the expression. We have $17 - (-194)$.
• Step 5: Simplify the subtraction, remembering that subtracting a negative number is equivalent to adding a positive number. So, $17 - (-194) = 17 + 194$.
• Step 6: Perform the final addition. Calculate $17 + 194 = 211$.

Therefore, the solution to the problem is $211$.

• Step 2: Perform the division
  The expression $-450:\frac{50}{-3}$ can be rewritten as $-450 \times -\frac{3}{50}$ since division by a fraction is equivalent to multiplication by its reciprocal.
• Calculate the multiplication
  $-450 \times -\frac{3}{50} = 450 \times \frac{3}{50} = 450 \times 0.06 = 27$.
• Step 3: Simplify the expression within parentheses
  The expression $(-3x) + (-14)$ simplifies to $-3x - 14$.
• Step 4: Combine all parts
  The complete expression $(-450:\frac{50}{-3}) - ((-3x) + (-14))$ simplifies to $27 - (-3x - 14)$.
• Simplify further
  This becomes $27 + 3x + 14 = 41 + 3x$.

Therefore, the solution to the problem is $41 + 3x$.

To solve this problem, we'll follow these equations:

• Step 1: Simplify $\frac{1}{4} \div \frac{8}{9} = \frac{1}{4} \times \frac{9}{8} = \frac{9}{32}$.
• Step 2: Simplify $\frac{3}{4} \div (4 \cdot 3) = \frac{3}{4} \div 12 = \frac{3}{4} \times \frac{1}{12} = \frac{3}{48} = \frac{1}{16}$.
• Step 3: Add the results from Steps 1 and 2: $\frac{9}{32} + \frac{1}{16}$. Convert $\frac{1}{16}$ to $\frac{2}{32}$ to have common denominators:
  $\frac{9}{32} + \frac{2}{32} = \frac{11}{32}$.
• Step 4: Subtract $\frac{11}{32}$ from $\frac{1}{2}$. Convert $\frac{1}{2}$ to $\frac{16}{32}$:
  $\frac{16}{32} - \frac{11}{32} = \frac{5}{32}$.

Therefore, the solution to the problem is $\frac{5}{32}$.
