Subtraction Practice
Take away small numbers, work with two digits, or practise exchanging across columns. The questions adjust as you go, and every answer can be worked through step by step.
No account, and the maths stays in your browser — more— less
This activity is for learning and practice. Anything it suggests is indicative only — it is not a formal assessment and not a substitute for a teacher or tutor.
Nothing you answer is sent to Zerdly. Progress is saved on this device only if you switch saving on, and you can delete it at any time. How Kids Maths handles data.
Set your country and age — change
Setting an age keeps the questions at the right level for that age. It does not lock anything — you can still try any topic, at any age, in any order. Levels are a guide only, not a curriculum.
Your age is not saved anywhere. Your country is remembered only if you have switched saving on.
Saving your progress
Nothing is being saved. You can practise as much as you like — when you close the tab, the session is gone.
Getting the most from it
- Subtraction is addition backwards. If you know 7 + 5 = 12, you already know 12 − 5. That is why addition facts come first.
- Exchanging is not “borrowing” anything back. When the top digit is too small, a ten is swapped for ten ones. “Show me why” lays that out with base-ten blocks.
- Watch for the flip. The most common slip is taking the smaller digit from the larger in each column regardless of which is on top — 52 − 27 becoming 35. If you do that, you will get an explanation aimed at exactly it.
School levels
School levels are a guide only. They show where a skill is usually taught in each country and are not taken from, aligned to, or endorsed by any curriculum authority. Your school may cover it earlier or later.
