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).

Front

What is a partial product?

Back

A partial product is the result of multiplying a single digit of one number by the entire other number in a multiplication problem. For example, in 23 x 4, the partial products are 20 x 4 and 3 x 4.

Front

What does the standard algorithm for multiplication involve?

Back

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

What is the multiplication fact for 5 x 6?

Back

The multiplication fact for 5 x 6 is 30.

Front

How do you represent 3 x 4 using addition?

Back

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.
