Exercise #1

$13-(7+4)=$

Step-by-Step Solution

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

$7+4=11$

Now we subtract:

$13-11=2$

Answer:

$2$

Exercise #2

$2-(1+1)=$

Step-by-Step Solution

To solve the expression $2 - (1 + 1)$ , follow these steps:

First, evaluate the expression inside the parentheses: $1 + 1$ .
This gives $2$ .
Now replace the parentheses with this result, transforming the expression to $2 - 2$ .
The result of $2 - 2$ is $0$ .

Therefore, the solution to the expression is $0$ .

Exercise #4

$100-(5+55)=$

Step-by-Step Solution

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

Step 1: Calculate the sum inside the parentheses.
Step 2: Subtract the result of the sum from 100.

Now, let's work through each step:
Step 1: Calculate $5 + 55$ , which gives $60$ .
Step 2: Perform the subtraction $100 - 60$ , which equals $40$ .

Therefore, the solution to the problem is $40$ .

Frequently Asked Questions

Everything you need to know about Additional Arithmetic Rules

What is the subtraction of a sum rule in arithmetic?

The subtraction of a sum rule states that a-(b+c) = a-b-c. This means when subtracting a sum in parentheses, you can distribute the negative sign to each term inside the parentheses. For example, 21-(7+2) = 21-7-2 = 12.

How do you solve subtraction of difference problems?

Use the rule a-(b-c) = a-b+c. When subtracting a difference, distribute the negative sign: the first term becomes negative and the second term becomes positive. For instance, 33-(9-3) = 33-9+3 = 27.

What is division by product rule and how does it work?

The division by product rule is a:(b·c) = a:b:c. You can divide by each factor separately instead of multiplying first. Example: 50:(2·5) = 50:2:5 = 25:5 = 5, which equals 50:10 = 5.

How is division by quotient different from division by product?

Division by quotient follows the rule a:(b:c) = a:b·c. You divide by the first term and multiply by the second term. For example, 48:(6:2) = 48:6·2 = 8·2 = 16, or solve parentheses first: 48:3 = 16.

Why do these arithmetic rules work with algebraic expressions?

These rules apply to algebraic expressions because they follow the same mathematical properties as numbers. The distributive property, associative property, and order of operations remain consistent whether using numbers or variables.

When should I use the rule vs order of operations?

Both methods give the same result. Use the rule method when you want to practice distributive properties or when parentheses contain complex expressions. Use order of operations when the calculation inside parentheses is simple and quick to compute.

What are common mistakes with subtraction of difference problems?

The most common mistake is forgetting that minus times minus equals plus. In a-(b-c), students often write a-b-c instead of a-b+c. Remember: the negative sign changes both terms in the parentheses.

How can I remember these arithmetic rules easily?

Use these memory aids: 1) Subtraction distributes to all terms, 2) Division by product splits into separate divisions, 3) Division by quotient flips the second operation (division becomes multiplication), 4) Practice with simple numbers first before using variables.
