Solver FAQ
Is the All Ten solver free?
Yes. Type in any four numbers and the solver instantly shows a valid expression for every target from 1 to 10, with step-by-step working. No account, no download.
Does the solver allow concatenation?
Yes. It follows the full Beast Academy rules: addition, subtraction, multiplication, division, brackets, fractions in intermediate steps, and joining digits together (2 and 4 can become 24).
Can every All Ten puzzle really be solved?
The daily puzzles on this site are pre-verified so all ten targets have solutions. Random four-digit sets are not always fully solvable — the solver will tell you honestly if a target has no answer.
