How do I get the sum of a text string?

I have a text string that changes at run time (it's an equation) - I have a second variable (number) that I'd like to make the sum of this string.

Is this possible? It's got me!

What is the string/text?

Would it be possible to make the string text display variables and do the math with those?

If not can the string/text be parsed in an easy way?

If not can it be parsed in a hard way?

The string is an equation that has operators and values appended to it at run time. Parsing is exactly what I want to do, but I've never done it - ideally I just want an expression that has the value of the string.

Why use the string if you have the values?

But like I said if you want to use the string it would be nescessary to know what the string looks like..

Sure thing - the string is basically "number" "operator" "number" (1+11 for example)

Quick example - the names were chosen poorly, but it demonstrates the idea that string changes at run time thanks to appends.

A hypothetical string would be - "1+12+2-4*8"

The simplest way would be to use the Browser.execJS() expression.

Amazing - thank you R0J0!

I'd create the string dynamically to be able to use things like controlling the decimals, etcetera:
