MultiplicationBy Katie McColly

Key Terms

Multiplier: the number or numbers being multiplied

Product: the answer

Multiplication Signs: x * ∙Example: 2 x 3 = 62 and 3 are both multipliers and 6 is the

product

What is Multiplication?

Multiplication is nothing but a shortcut for addition!

An equation that tells us how many times to add a number with itself

Example #1

What is 5 x 2 ? This equation is telling us to add 5 with

itself two times 5 + 5 = 10 So 5 x 2 = 10

5 x 2 is the same problem as 2 x 5

We would now be adding 2 with itself 5 times!

2

+ 2

+ 2+ 2+ 2= 10

So 5 x 2 = 10

Multiplying by 1

Any number multiplied by one is the same number

Why??? That number is only being added once

so it stays the same

For Example

3 x 1= ? We are adding 3 only 1 time

So. .. ..

3 +Nothing Else= 3

Meaning that 3 x 1 = 3

This works with any number! LIKE…200 x 1 = 200Because 200 + nothing else = 200Or 1,000,000 x 1 = 1,000,000

This works in reverse too 1 x 3 for example

1 +1 +1 =3

So 1 x 3 = 3

The Zero Rule

Any number multiplied by zero will equal zero

WHY??? You aren’t multiplying the number by

anything

Examples

7 x 0 = 0 0 x 4 = 0 1 x 0 = 0 255 x 0 = 0 Any number x 0 = 0
