Results
Tool/Solver to solve fill the blanks calculations where the operators are missing. A calculation/equation with blanks is a mathematical exercise consisting of finding the missing operation (addition, subtraction, multiplication, division).
Summary

## Answers to Questions

### How to solve a calculation with blank operators?

The resolution of calculation with blank is a common school puzzle consists of identifying the possible operations, for example, it is impossible to divide by 0. Also multiplications introduce large numbers, so they must be avoided if the result is small. Non-integer divisions are generally to be avoided.

Example: 1 ? 2 ? 3 = 0 has for solution 1 + 2 - 3 = 0

Example: (1 ? 2 ? 3) ? 4 = 0 has for solution (1 + 2 - 3) * 4 = 0

dCode also has a similar solver for numbers with missing digits.

### How does the missing numbers solver works?

The program handles the 4 operators (addition +, subtraction -, multiplication * and division /), the equal sign =, but also the upper and lower operators > and <.

The blanks should be replaced with ? (Question marks).

The solver uses a brute-force method, ie it tries all combinations and displays possible combinations.

The solver is limited to numbers and does not accept variables or letters in the calculation. Also, parentheses cannot be guessed and must be supplied.
