Subtract hundreds

Subtract hundreds helps children practise subtracting full hundreds by working with the hundreds digit only — for example 900 − 300 = 6 hundreds = 600. Read the short guide and look through the examples before choosing online practice or a printable worksheet.

How to solve this

  • Subtracting hundreds: focus on the hundreds digits only, then attach "00": 800 − 300 = 5 hundreds = 500.
  • If the hundreds don't reduce to a simple fact, write it as a normal subtraction of the leading digits.
  • Check by adding: 500 + 300 must give back 800.
