Breaking Apart Addends to Solve Math

Reorganizing addends will help to simplify complex math problems.
  • Remember that any number value you take away from one addend must be added to another within the problem, or else your sum will be incorrect.
  • Instead of restructuring simply for tens and ones, you can also restructure to create groups of tens -- numbers that end in zero. For example, in the problem 27 + 13 = ___, you could combine 27 and the 3 from 13 to get 30 + 10, which produces the same sum of 40. You can also restructure to create groups of fives along with tens: 22 + 13 = 35 becomes 20 + 10 + 5 = 35. Whichever organization you choose for a problem, remember that you are reorganizing the numbers to make the problem easier.
