About Subtraction

What is Subtraction?

Subtraction is finding the difference between numbers or taking away from a quantity. It's the inverse of addition.

Why is it important?

Subtraction helps children understand comparison, change, and missing parts. These concepts are essential for problem-solving and understanding negative numbers later.

Common Challenges

  • Confusing the order of numbers (subtracting the larger from smaller)
  • Difficulty with regrouping (borrowing)
  • Not connecting subtraction to addition fact families

Tips for Practice

  • Use number lines to visualize 'counting back'
  • Practice fact families (3+4=7, 7-4=3, 7-3=4)
  • Start with concrete objects before moving to abstract problems

How to Help Your Child

For regrouping (borrowing), your child crosses out the digit in the next column, reduces it by 1, and adds 10 to the current column. Use the phrase 'borrow from your neighbor' — it's the same method you learned, possibly with a different name.
