@dubstar-04 complete

[dubstar-04]

Cool feature. Need to consider the following:

Order of operations (BIDMAS) :
4+2*5 = 14 but calculates linearly to 30

Negative numbers don't return a result:
-100+50

[dubstar-04]

Should be able to distil this down to a much simpler expression.

[dubstar-04]

it could be possible to simplify calculations.

This is janky but shows an extreme example:

const input = '4+2*5';
const calculation = Function('return ' + input)();
console.log('calculation: ', calculation);

AutoCAD Expressions, use the CAL command:

(BIDMAS)

This is standard method of calculating without brackets. This is also how a calculator would return the answer if you typed it in literally. Should handle better though.

Guidance on this;

Will look at a better solution.
