This countdown solver allows finding a target number from a set of integer in using arithmetic operations.

arithmetic_solver online

The countdown maths solver is able to find a solution to the **countdown numbers game** or its derivative games as mathador.

This **countdown solver** allows **to find a solution** to free
game countdown numbers,
ie, it provides the **countdown solution**.
This solver is able to calculate a target number from the numbers placed in setting and using the four basic operations :
addition, subtraction, division and multiplication.
When the **solver** can **find** a **countdown solution**, it is returned, otherwise
the **countdown** **solution** which is closest to the target number is returned.

For example, to find 221, with the numbers 25 5 12 9 and 11, enter: arithmetic_solver(`221;25;5;12;9;11`). The countdown maths solver will return a solution : {25-12=13;13+11=24;24*9=216;216+5=221}.

Mathador is a game inspired by the countdown numbers game, the arithmetic solver online is a **mathador solver**
he is able to find solutions to mathador game.

arithmetic_solver(target_number;number1;number2;number3;...;numberN), where target number is the target number to find and number1, number2, nombreN, numbers to use to find the target number.

This example shows how to use the **calculator countdown numbers**.

To find 39 with the numbers 4, 6, 1, 6, 5, enter :

arithmetic_solver(`39;4;6;1;6;5`), returns {4-1=3;6*6=36;36+3=39} Calculate online with arithmetic_solver (countdown solver)
