In the following problems, add the numbers using tidy whole number and compensating to solve the problems below. Then, CREATE a problem of your own and explain how you solved it step by step on your BLOG.
Example:
? + 3.98 = 7.04
3.98 + ? = 7.04
3.98 + 0.02 =4.0
4 + 3 =7
7 +.0.04 = 7.04
So ? = 3.06

1. 4.64 + 5.36 = 10.87 4. 7.33 + 26.21 = 34.54
2. 8.23 + 4.43 = 13.56 5. 22.38 + 43.26 = 65.64
3. 3.39 + 11.14 = 14.53 6. 14.10 + 84.74 = 98.84
5.15.15+ 4.98 = 20.20
+0.2
15.15 + 5.05 = 20.20
