Target0
Tap a number, an operation, then a second number: the result replaces both. You don’t have to use every number.
Frequently asked questions
Is there always a solution?
Yes: every set of numbers is built from a real calculation, so the target can always be reached. “Show a solution” reveals one.
Do I have to use every number?
No, you just need to hit the target exactly; some numbers can be left over.
What age is it for?
The medium level suits children from 7 with addition and subtraction; the expert level is a real challenge for teens and adults.
