24 Game(24点) / Countdown Solver and Even More

This page helps you to use operators(+, -, ×, ÷) and given numbers to get any desired results

1. Enter numbers, separate with ","(comma), e.g. "11,11,11,12";
2. To calculate the range these numbers can generate (e.g. 4, 2, 1 can generate all numbers between 1 to 10), set "Lower limit" and "Upper limit" to be valid integers.
3. To calculate one specific result (e.g. 24), set "Lower limit" = "Upper limit" = your integer.
**Only +, -, ×, ÷, and (), are considered.

Interesting facts:
you can use
    2 and 1 to calculate the number from 1 to 3;
    4, 2 and 1 to calculate 1 ~ 10;
    [4, 4, 6, 6, 60] to get 1 ~ 100;
    [2, 8, 9, 12, 13] to get 1 ~ 271;
