For example:
For homework we had to do p.46 A. (1-45). We had to answer three questions using algebra tiles.
For example:
Here are the questions and answers for p.46 A.
1. (-8)-(+2) 2. (-9)-(+3)
(-8)+(-2)= -10 (-9)+(-3)= -12
3. (-10) -(+5) 4. (-8)-(-3)
(-10)+(-5)= -15 (-8)+(+3)= -5
5. (-7)-(+7) 6. (-4)-(-6)
(-7)+(-7)= -14 (-4)+(+6)= 2
7. (-3)-(+3) 8. (-5)-(-9)
(-3)+(-3)= -6 (-5)+(+9)= 4
9. (-9)-(-12) 10. (-12)-(+18)
(-9)+(+12)= 3 (-12)+(-18)= -30
11. (-8)-(+4) 12. (+4)-(-9)
(-8)+(-4)= -12 (+4)+(+9)= 13
13. (+6)-(-12) 14. (-9)-(-15)
(+6)+(+12)= 18 (-9)+(+15)= 6
15. (-15)-(+6) 16. (+15)-(+6)
(-15)+(-6)= -21 (+15)+(-6)= 9
17. (+4)-(-3)
(+4)+(+3)=7
18. (+3)-(-2)
(+3)-(+2)= 5
19. (-5)-(-7) 20. (-2)-(+4)
(-5)+(+7)=2 (-2)+(-4)= -6
21. (-19)-(-18) 22. (+10)-(+19)
(-19)+(+18)= -1 (+10)+(-19)= -9
23. (-17)-(+23) 24. (+11)-(+14)
(-17)+(-23)= -30 (+11)+(-14)= -3
25. (+10)-(-16) 26. (+13)-(-12)
(+10)+(+16)= 26 (+13)+(+12)= 25
27. (-15)-(+6) 28. (-18)-(+14)
(-15)+(-6)= -21 (-18)+(-14)= -32
29. (0)-(-15) 30. (-13)-(+12)
(0)+(+15)= 15 (-13)+(-12)= -25
31. (+7)-(+3) 32. (-6)-(-3)
(+7)+(-3)= 4 (-6)+(+3)= -3
33. (-8)-(-6) 34. (+6)-(-3)
(-8)+(+6)= -2 (+6)+(+3)= 9
35. (-7)-(-8) 36. (-4)-(+2)
(-7)+(+8)= 1 (-4)+(-2)= -6
37. (+4)-(+2) 38. (-3)-(-14)
(+4)+(-2)=6 (-3)+(+14)= 11
39. (-3)-(+5) 40. (+8)-(-6)
(-3)+(-5)= -8 (+8)+(+6)= 14
41. (+5)-(-8) 42. (-8)-(+2)
(+5)+(+8)= 13 (-8)+(-2)= -10
43. (+7)-(-9) 44. (-8)-(+6)
(+7)+(+9)= 16 (-8)+(-6)= -14
45. (-7)-(-9)
(-7)+(+9)= 2
Here is a video on how to subtract integers:
goood job ella .

Good job Jowella. Only one little thing I have to point out...there are a lot of spaces which probably aren't your fault anyways.

Dammit, Good job. I guessed on that day I didn't have to do my h.w, just copy off yours. Well done and good explaining on some of your answers. Keep it up:)
