It's a simple yet quite practical quiz on one-step equations. For a formal introductory definition on the topic, it's an algebraic equation which is solved in just one step, that's why it's called so. Now, here you are going to face more than 20 questions to shake your brain cells (probably). So, let's get started.

• 1.

### What is the inverse operation for multiplication?

• A.

• B.

Subtraction

• C.

Division

C. Division
Explanation
The inverse operation for multiplication is division. Division is the process of splitting a number into equal parts or groups. It is the opposite of multiplication, where you combine or repeat a number a certain number of times. When you divide a number by another number, you are essentially undoing the multiplication process and finding the original number that was multiplied. Therefore, division is the correct answer as the inverse operation for multiplication.

### What is the inverse operation for addition?

• A.

Subtraction

• B.

Multiplication

• C.

Division

A. Subtraction
Explanation
The inverse operation for addition is subtraction. When two numbers are added together, subtracting one of the numbers from the sum will give you the other number. Subtraction undoes the effect of addition and brings the numbers back to their original values.
