Operations on whole numbers

Front

What is multiplication?

Back

Multiplication is a mathematical operation that represents the repeated addition of a number. For example, 4 x 3 means adding 4 three times: 4 + 4 + 4 = 12.

Front

What is a product in multiplication?

Back

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

Front

What is the commutative property of multiplication?

Back

The commutative property states that changing the order of the numbers in a multiplication problem does not change the product. For example, 3 x 4 = 4 x 3.

Front

What is the associative property of multiplication?

Back

The associative property states that the way in which numbers are grouped in multiplication does not change the product. For example, (2 x 3) x 4 = 2 x (3 x 4).

Front

What is a factor?

Back

A factor is a number that is multiplied by another number to get a product. For example, in 6 x 4 = 24, both 6 and 4 are factors.

Front

What is a partial product?

Back

A partial product is the result of multiplying a single digit of one factor by the entire other factor, often used in long multiplication.

Front

How do you calculate the total number of items in groups?

Back

To find the total number of items in groups, multiply the number of groups by the number of items in each group. For example, if there are 5 groups of 4 items, the total is 5 x 4 = 20.

Front

What is the standard algorithm for multiplication?

Back

The standard algorithm involves multiplying numbers digit by digit, starting from the rightmost digit, and carrying over any values as needed.

Front

What is the difference between an equation and an expression?

Back

An equation shows that two expressions are equal, while an expression is a combination of numbers and variables without an equality sign.

Front

What is the distributive property?

Back

The distributive property states that a(b + c) = ab + ac. It allows you to multiply a number by a sum by distributing the multiplication.
