- 4. Example #1What is5 x 2 ?This equation is telling us to add 5with itselftwo times5 + 5 = 10So 5 x 2 = 10
- 5. 5 x 2is 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 x2 = 10
- 8. Multiplying by 1Anynumber multiplied by one is the same numberWhy???That number is only being added once so it stays the same
- 9. For Example3 x1= ?We are adding 3 only 1 time
- 10.

- 12. Meaning that 3x 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 inreverse too1 x 3 for example1+1+1=3So 1 x 3 = 3
- 14. The Zero RuleAnynumber multiplied by zero will equal zeroWHY???You aren’t multiplying the number by anything
