tens.

4,259 – 2,171 =

Problem 2:

Regroup 1 thousand into 10 hundreds using the subtraction algorithm.

1. Use the standard algorithm to solve the following subtraction problems.

a. 7,525 - 3,502 =

d. 4,625 - 435 =

Directions: Draw a tape diagram to represent each problem. Use numbers to solve and write your answer as
a statement. Check your answers.
