I want to convert the text to numbers to get a mathematical result

Question

echo $equation //outputs (5+10)-8+2*2

I want to show this result 11

Uuse `eval` on the string and the result would be the mathematical result. — IT goldman, Jul 02 '22 at 17:33
Please read: [How do I format my posts using Markdown or HTML?](https://stackoverflow.com/help/formatting) because `echo $equation = "(5+10)-8+2*2";` will not even assign a value to `$equation`.... — Luuk, Jul 02 '22 at 17:36
