term, when the [Do] clicked. (The [^] takes all values left of it as
base, all to the right as exponent.) Trade values in and out of Memory to control.

Write legitimate Java Script expressions --evaluated according to interpreter's parser. NaN is Not a Number, can often correct. Programming is on the highest level. Definitely view source code. Programming experience is desireable, but with minimal effort, one's most-used functions can be inserted in the source (well commented for the purpose).
