Math 4 Properties of Addition that would help you
- 3. There are 3 properties of Addition:
- 4. Commutative Property Associative Property Identity Property
- 6. The word commutative comes from the verb “to commute”. Commutative Property
- 7. Commuting means changing, replacing, or exchanging Commutative Property
- 8. The digits change their order, but the answer stays the same! Commutative Property
- 9. A + B = B + A Commutative Property
- 10. Commutative Property 2 + 3 = 5 3 + 2 = 5
- 11. Commutative Property 66 + 11 = 77 11 + 66 = 77
- 13. To associate means to group numbers together . Associative Property
- 14. In math, we use parenthesis to show groups. Associative Property
- 15. In the order of operations, always do the problem or number in the parenthesis FIRST! Associative Property
- 16. The digits stay the same, but are grouped together differently. Associative Property
- 17. The digits are grouped together differently. BUT… • The answer is always the same! Associative Property
- 18. (A + B)+ C = A + (B + C) Associative Property
- 19. 850 + (1 + 10) = 861 (850 + 1) + 10 = 861 Associative Property
- 20. (3+5) + 6 = 14 3+(5 + 6) = 14 Associative Property
- 22. I am me! You cannot change My identity! Identity Property
- 23. What do you think is this number that when you add it to a number it will not change its value? Identity Property
- 24. When you add a zero to any number, the sum is that same as that number. Identity Property
- 27. Zero is the only number you can add to something and see no change. Identity Property
- 28. A + 0 = A Identity Property
- 29. 234 + 0 = 234 Identity Property
- 31. Directions: Write CP if it is Commutative property, AP if it is Associative Property, IP if it Identity Property.
