  1. This is a strategy you may use to make addition easier.
  2. I call it "adding up to ten strategy", that requires to find any numbers that add up to 10.
  4. Example:
  5. Find the sum of: 7 + 8 + 3 + 2 + 5
  6. 7+3 is 10,
  7. 8+2 is another 10, which makes 20,
  8. Plus 5 is 25
  9. The total is 10+10+5 = 25
  10. Easy!
