Tool to solve missing number/fill the blanks puzzles. A calculation with missing numbers (blanks), as a addition, subtraction, multiplication, division, is a mathematical puzzle which consists in finding the missing number or digit.

Solving is similar to a cryptarithm and uses deduction and extraction of parts of the calculation.

??5 + 42? = 539 => 115 + 424 = 539

12 + 23 = ? has no solution but 12 + 23 = ?? has for solution 12 + 23 = 35

For example, it is useful to calculate digits at extremities, or check individually calculations to the ten digits, or the hundreds digit etc.

dCode also has a cryptarithm solver (where blanks are letters), a mathematical equation solver or even a countdown game calculation tool.

dCode solver allow usual operators like additions +, subtractions -, multiplications * and divisions /. It also handles comparators superior and inferior > and <.

The blanks have to be replaced by ? (interrogation marks). There is no limit but above 7 or 8, the calculation will be very long.

1+?=3 is solved with 1+2=3

2*?=8 is solved with 2*4=8

This solver uses a brute-force method, this means that it tries all combinations and display the possible ones.
