What is the inverse operation for multiplication?
- A.
Addition
- B.
Subtraction
- C.
Division
Correct Answer
C. DivisionExplanation
The inverse operation for multiplication is division. When we multiply a number by another number and then divide the result by the same number, we get back to the original number. Division undoes the effect of multiplication, just like subtraction undoes addition and vice versa.Rate this question:

What is the inverse operation for an addition?
- A.
Subtraction
- B.
Multiplication
- C.
Division
Correct Answer
A. SubtractionExplanation
The inverse operation for addition is subtraction. This is because addition and subtraction are opposite operations. When we add a number to another number, we can undo the addition by subtracting the same number from the sum. For example, if we have 5 + 3 = 8, we can find the original numbers by subtracting 3 from 8, which gives us 8 - 3 = 5.Rate this question:

Multiplication
Correct Answer
C. MultiplicationExplanation
The inverse operation for division is multiplication. When we divide a number by another number, we are essentially finding how many times the divisor can fit into the dividend. To undo this operation and get back to the original number, we need to multiply the quotient by the divisor. Multiplication undoes division, making it the correct answer.Rate this question:
