Multiply Multiple Digits

10 x 10 x 10

5 x 20 x 3

100 x 2 x 5=

5 x 5 x 5 x 5 =

6 x 5 x 10 x 2

Break down the number into addends.

Distribute your number out.

Multiply your addends by your number.

Add your answers together.

256 x 3 = (200 x 3) + (50 x 3) + (6x3) = 600 + 150 + 18 = 768.

• partial products

• distributive property

• regroup

• standard form

The products of each place are found by themselves. They are then added together.

256 x 3 = (200 x 3) + (50 x 3) + (6x3) = 600 + 150 + 18 = 768.

• partial products

• distributive property

• regroup

• standard form

When you multiply each place in order (ones, tens, hundreds, etc.) to get a final answer. It is the way that most people multiply.

123 x 2 = 246.

• Area Model

• Standard Algorithm

• Commutative Property

• Distributive Property

When you multiply numbers by finding the area of a rectangle. (You multiply length times width.)

• Area model

• Distributive Property

• Associative Property

• Commutative Property

The order of the addends or factors does not change the sum nor the product. You flip flop the numbers around. 45 x 23 = 23 x 45
