Question

When do you use the reverse order of operations?

A) When simplifying an expression or equation
B) When plugging in a number for the variable and solving
C) When solving an equation for the variable

Answer 1

The reverse order of operations is used when simplifying an expression or equation.

Step-by-step explanation:

The reverse order of operations is used when simplifying an expression or equation.

It involves working backwards from the final desired result to determine the steps needed to reach that result.

For example, if you want to simplify the expression 3 + 4 × 5, you would first perform the multiplication (4 × 5 = 20), and then add the result to 3 (3 + 20 = 23).

This is different from the usual order of operations, which states that you should perform the multiplication first, and then the addition (3 + 4 = 7, and then 7 × 5 = 35).
