Multiplication & Division Review

Multiplication is a mathematical operation where a number is added to itself a certain number of times. For example, 3 x 4 means adding 3 four times: 3 + 3 + 3 + 3 = 12.

Division is a mathematical operation where a number is split into equal parts. For example, 12 ÷ 3 means splitting 12 into 3 equal parts, which equals 4.

The product is the result of multiplying two or more numbers together. For example, in 5 x 6, the product is 30.

The quotient is the result of dividing one number by another. For example, in 20 ÷ 4, the quotient is 5.

A number is even if it can be divided by 2 without a remainder. For example, 4 and 68 are even numbers.

A number is odd if it cannot be divided by 2 evenly. For example, 3 and 7 are odd numbers.

A factor is a number that divides another number without leaving a remainder. For example, 2 and 3 are factors of 6.

A number sentence is a mathematical statement that includes numbers and operations, such as addition, subtraction, multiplication, or division.

To find the total number of items in equal groups, multiply the number of groups by the number of items in each group. For example, 4 groups of 5 items each equals 4 x 5 = 20.

Multiplication and division are inverse operations. If you know that 4 x 5 = 20, you can also say that 20 ÷ 5 = 4.
