Multiplication is repeated addition. It involves multiplying a multiplier by itself a specified number of times to get the product. The order of the multipliers does not matter. Multiplying any number by 1 leaves the number the same. Multiplying any number by 0 results in 0 because nothing is being added.

1. MultiplicationBy Katie McColly

2. Key TermsMultiplier: the number or numbers being multipliedProduct: the answerMultiplication Signs: x * ∙Example: 2 x 3 = 62 and 3 are bothmultipliers and 6 is the product

3. 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

4. Example #1What is 5 x 2 ?This equation is telling us to add 5with itselftwo times5 + 5 = 10So 5 x 2 = 10

5. 5 x 2 is the same problem as 2 x 5We would now be adding 2 with itself 5 times!

6. 2 + 2+ 2+ 2+ 2= 10

7. So 5 x 2 = 10

8. Multiplying by 1Any number multiplied by one is the same numberWhy???That number is only being added once so it stays the same

9. For Example3 x 1= ?We are adding 3 only 1 time

10. So.....

11. 3+Nothing Else= 3

12. Meaning that 3 x 1 = 3This works with any number!LIKE…200 x 1 = 200Because 200 + nothing else = 200Or 1,000,000 x 1 = 1,000,000

13. This works in reverse too1 x 3 for example1+1+1=3So 1 x 3 = 3

14. The Zero RuleAny number multiplied by zero will equal zeroWHY???You aren’t multiplying the number by anything

15. Examples7 x 0 = 00 x 4 = 0 1 x 0 = 0255 x 0 = 0 Any number x 0 = 0
