Perform the operations without a calculator. Show work by plotting the operations on a
number line.
1. There are several ways to add or subtract integers. Some think of money debts, others think
of protons versus electrons. The following example is showing how addition is about gaining
and subtraction about losing in terms of the real number line.
-4 + 9
7 - 5
-3 - 3
1 - 7
1 + 3
= 5
= 2
= -6
= -6
= 4
-4 0 1 2 3 4 5 -6 -5 -4 -3 1 2 3 4
Simplify the following by doing the indicated operation:
2. - 4 - 9
3. -7 – 5
4. -3 + 3
5. -1 – 7
6. 1 - 3
7. -5 – 9
8. 8 – 3
9. 53 – 42
10. 31 – 82
11. - 44 + 53
12. - 35 + 35
13. 23 – 17
14. 2 – 4 – 6
15. 2 + (- 4) – 6
16. 0 – 2 + 6
