Use the U.S. standard algorithm for subtraction to solve each problem. Check each of your answers by using another method.

  • 1 487 − 209 = _______________

    Here is how I solved it using the U.S. standard algorithm: Here is the second way I solved it:
  • 2 1,265 − 795 =

    Here is how I solved it using the U.S. standard algorithm: Here is the second way I solved it:

NOTE

Students practice strategies for subtraction by solving a problem in two ways, including the U.S. standard algorithm.
