# How to evaluate a linear expression using integer multiplication with addition or subtraction?

Integers are the numbers that can be positive, negative, or zero, numbers with no fractional part.

## Answer: Follow the operation on integers to evaluate a linear expression using integer multiplication with addition or subtraction.

In the case of integers, addition operation might lead to an increase or decrease in the value of the given number. If we add a negative integer, the value of the given number will decrease and if we add a positive integer the value will increase.

**Explanation:**

Suppose we have an expression 4x - y and we have to find the value evaluate the expression for x = 2 and y = -5

Substituting x = 2 and y = -5, we get

4 (2) - (-5) = 8 + 5 = 13

So, following the operation on integers, we can easily evaluate a linear expression using integer multiplication with addition or subtraction.
