Binary operations (with 2 inputs)

Task

Number of solutions:

Solutions

Number of found solutions: -

	

Usual task:

Example: Inserting operators between digits so that the result is 10.

1 2 5 5

There are given 4 digits from 1 to 9. The task is to fill in numerical operators (+, −, ×, ÷, √ and !) so that the result of the created expression is 10.

Variations:

However, the program has more options. It is possible to change the number of entered digits, allowed operations and result. Finding a solution for higher number of digits may take a very long time. If you don't want to find all solutions, but only a limited number, check Find the first X solutions, it'll be faster.

There may be no solution for a given input.
