In today's class, we learned how to add and subtract integers in standard form. In standard form we combine integers. For example, -4-3= -7. It's owe 4, owe 3. As you can see, there are no more "training wheels". You also DON'T add the opposites.
For today's homework, we got a new booklet that's green. On the first page, we do all the questions in part one and all the even numbers in part two.

PART ONE
1. 6+8=
2. -4-3=
3. 15-2=
4. 14+8=
5. 9-23=
6. -5-8=
7. -12+25=
8. -11+12=
9. 22-8=
10. -7-8=
... and so on.

PART TWO
2. 5-(-8)-(7)+5=
4. 5-2-(-7)-(-3)=
6. -7-(-5)-(-7)-8=
8. -7-(-5)-(5)+8=
10. -(-2)-(-6)-15=
12. -2-3+4-6=
14. 2-7-8=
16. 3-9+8=
... and so on.


Sorry if I didn't explain well or didn't make sense. If I'm wrong, just comment. :)
