# Missing Operators Equation Solver

## Missing Numbers Calculations Solving

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

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

The resolution 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.

### 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.
