Parentheses in simple Order of Operations: Solving the problem

To solve the equation, follow these steps:

1. Start by solving the expression inside the parentheses: $12 + 8$.

2. Calculate $12 + 8$ to get $20$.

3. Now divide the result by 4: $20 \div 4$.

4. Calculate $20 \div 4$ to get $5$.

Therefore, the final answer is $5$.

To solve the equation, follow these steps:

1. Start with the expression inside the parentheses: $50 - 10$.

2. Calculate $50 - 10$ to get $40$.

3. Now multiply the result by 2: $40 \times 2$.

4. Calculate $40 \times 2$ to get $80$.

Therefore, the final answer is $80$.

Let's simplify this expression while following the order of operations which states that exponents come before multiplication and division, which come before addition and subtraction, and that parentheses come before all of them,

We will therefore start by simplifying the expression inside the parentheses and calculate the result of the addition within them, then - we will first perform the division operation:

$(85+5):10= \\ 90:10= \\ 9$

$$Therefore, the correct answer is answer A.

Apply the distributive property and proceed to multiply each term inside of the parentheses by 187:

$187\times8-187\times5=$

Solve the first multiplication problem vertically, making sure to solve it in the correct order (ones multiplied by ones, ones multiplied by tens, ones multiplied by hundreds )

$187\\\times8$

We should obtain the following result: 1496

Proceed to solve the second multiplication problem vertically, once again making sure to solve it in the correct order (ones multiplied by ones, ones multiplied by tens, ones multiplied by hundreds )

$187\\\times5$

We should obtain the following result: 935

Now to tackle the next problem:

$1496-935=$

We should once again solve this vertically. Make sure to align the digits properly, ones under ones, tens under tens, etc.:

$1496\\-935$

Subtract ones from ones, tens from tens, etc., to obtain the final result: $561$

Let's simplify this expression while maintaining the order of operations.

Let's start by solving what's in the parentheses:

$29-4=25$

Now we get the expression:

$25:5=$

In the next step, to make the division easier, we'll break down 25 into two smaller factors that are divisible by 5:

$(20+5):5=$

Let's divide each factor in the parentheses by 5:

$(20:5)+(5:5)=$

We'll solve each expression in the parentheses and obtain:

$4+1=5$

According to the order of operations rules, we must first solve the expressions inside of the parentheses:

$15-9=6$

$7-3=4$

We obtain the following expression:

$6\times4=24$

Let's simplify this expression while following the order of operations which states that exponents come before multiplication and division, which come before addition and subtraction, and that parentheses come before all of them,

Therefore we'll start by simplifying the expression inside the parentheses and perform the subtraction within them, then since division comes before subtraction, we'll first perform the division operation and then the subtraction operation

$10-(10-4):2= \\ 10-6:2= \\ 10-3=\\ 7$Therefore the correct answer is answer D.

To solve the expression $10-(5+2\times2)\div3$, follow the order of operations:

1. Parentheses: Calculate inside the parentheses first, performing multiplication first: $2\times2 = 4$. Therefore, it is $5+4=9$.

2. Division: Now, we have $10-9\div3$. Perform the division: $9\div3 =3$.

3. Subtraction: $10-3=7$,

Thus, the answer is $7$.

According to the order of operations, we will first solve the expression in parentheses.

We will solve the exercise vertically, making sure to align digits properly - ones under ones, tens under tens, and so on. Note that the decimal point is in place:

$1.4\\-0.3\\$

And we get the result:

$1.1$

Now we have the expression:

$1.1\times10=$$$

The above expression doesn't need to be calculated, we simply need to move the decimal point one place to the right, since we are multiplying by ten, meaning we're adding a tens place.

Therefore, we get the result:

$11$

To solve $15-3\times(2+1)$, start by calculating the expression inside the parentheses, $2+1 = 3$.

Next, multiply by 3: $3\times3 = 9$.

Now, subtract from 15: $15-9 = 6$.

The final answer is 6.

To solve $20\div(4+1)-3$, start by simplifying inside the parentheses: $4+1 = 5$.

Next, divide 20 by 5: $20\div5 = 4$.

Then subtract 3: $4-3 = 1$.

The final answer is 1.

According to the order of operations, we will first solve the expression in parentheses:

$5+0=5$

Now we will get the expression:

$25\times5=$

Let's solve the expression vertically:

$25\\\times5$

We will be careful to solve the expression in the correct order, ones with ones and then ones with tens

And we will get:

$125$

According to the order of operations, we'll first solve the exercises in parentheses:

$(16-6)=10$

$(7-3)=4$

We should obtain the following exercise:

$10\times9+4$

We'll place the multiplication exercise in parentheses to avoid confusion in the rest of the solution:

$(10\times9)+4=$

According to the order of operations, we'll solve the multiplication exercise and then add:

$90+4=94$

According to the rules of the order of operations, we first solve the exercise within parentheses:

$4+5=9$

Now we obtain the exercise:

$2\times3-9:2=$

We place in parentheses the multiplication and division exercises:

$(2\times3)-(9:2)=$

We solve the exercises within parentheses:

$2\times3=6$

$9:2=4.5$

Now we obtain the exercise:

$6-4.5=1.5$

Let's simplify this expression while adhering to the order of operations which states that exponents come before multiplication and division, which come before addition and subtraction, and that parentheses take priority over all.

In our expression, there is a term in parentheses that needs to be multiplied. We'll start by simplifying this expression, remembering that division comes before addition, so we'll first perform the division operation within the parentheses and then the addition operation in this expression:

$4+(6+6:3)\cdot2= \\ 4+(6+2)\cdot2= \\ 4+8\cdot2=$

Let's continue simplifying the expression we that we got in the last step. Since multiplication comes before addition, we'll first calculate the multiplication in the expression and then perform the addition operation:

$4+8\cdot2= \\ 4+16= \\ 20$

To summarise:

$4+(6+6:3)\cdot2= \\ 4+8\cdot2= \\ 20$

Therefore the correct answer is answer C.

Let's simplify this expression while following the order of operations which states that exponents come before multiplication and division, which come before addition and subtraction, and that parentheses come before all of them,

We will start by simplifying the expression inside the parentheses and calculate the result of the subtraction within them, then - since division comes before subtraction, we will first perform the division operation and then perform the subtraction operation:

According to the order of operations, first we solve the exercise within parentheses:

$30+6=36$

Now we solve the exercise

$36:4\times3=$

Since the exercise only involves multiplication and division operations, we solve from left to right:
