Lesson 11 Multiplication Flashcard

Front

What is multiplication?

Back

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

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 are partial products?

Back

Partial products are the results of multiplying each digit of one number by each digit of another number, and then adding those results together. For example, in 23 x 4, you can calculate (20 x 4) + (3 x 4) = 80 + 12 = 92.

How do you use the distributive property in multiplication?

Back

The distributive property states that a(b + c) = ab + ac. This means you can distribute the multiplication over addition. For example, 3(4 + 5) = 3 x 4 + 3 x 5.

What is the expression to find the total number of pencils if there are 4,207 book bags and each has 3 pencils?

Back

(4,000 x 3) + (200 x 3) + (7 x 3) is the expression to find the total number of pencils.

What does it mean to multiply by 10?

Back

Multiplying a number by 10 shifts its digits one place to the left. For example, 5 x 10 = 50.

Front

What is the commutative property of multiplication?

Back

The commutative property states that changing the order of the numbers you are multiplying does not change the product. For example, 4 x 5 = 5 x 4.

Front

What is an array in multiplication?

Back

An array is a visual representation of multiplication using rows and columns. For example, a 3 x 4 array has 3 rows and 4 columns, representing 3 x 4 = 12.

Front

What is the identity property of multiplication?

Back

The identity property states that any number multiplied by 1 remains the same. For example, 7 x 1 = 7.

Front

What is a factor in multiplication?

Back

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