Evaluate simple mathematical expressions as you type!
In most text input areas on most webpages, type your expressions between double square brackets. For example:
[[2+2]]
[[3-(4*.2)]]
[[(.5*.44-.2)^(1/5)+12]]
The expressions will be evaluated and the text replaced as soon as you type the second closing bracket:
[[2+2]]
--> [[4
[[3-(4*.2)]]
--> [[2.2
[[(.5*.44)^(1/5)+12]]
--> [[12.7387
The brackets remain open so you can perform successive operations quickly without touching the mouse. Simply add a third closing bracket when you're done to "exit" the calculator.
