Multiplication and Division

Front

What is multiplication?

Back

Multiplication is a mathematical operation that represents the repeated addition of a number. For example, 4 multiplied by 3 (4 x 3) is the same as adding 4 three times (4 + 4 + 4).

What is division?

Back

Division is a mathematical operation that represents the process of splitting a number into equal parts. For example, dividing 12 by 4 (12 ÷ 4) means splitting 12 into 4 equal groups, which results in 3.

How can you represent division as a repeated subtraction?

Back

Division can be represented as repeated subtraction by continuously subtracting the divisor from the dividend until reaching zero. For example, 12 ÷ 3 can be seen as subtracting 3 from 12 four times (12 - 3 - 3 - 3 - 3 = 0).

What is the relationship between multiplication and division?

Back

Multiplication and division are inverse operations. If a x b = c, then c ÷ b = a and c ÷ a = b.

What is a repeated addition sentence?

Back

A repeated addition sentence is a way to express multiplication using addition. For example, 3 x 4 can be expressed as 4 + 4 + 4.

Front

What is the formula for multiplication?

Back

The formula for multiplication is a x b = c, where 'a' and 'b' are the factors and 'c' is the product.

Front

What is the formula for division?

Back

The formula for division is a ÷ b = c, where 'a' is the dividend, 'b' is the divisor, and 'c' is the quotient.

How can you check your division answer?

Back

You can check your division answer by multiplying the quotient (result) by the divisor. If the product equals the dividend, your answer is correct.
