[TxMt] Enhancement of Math commands: overwrite previous results

Hi all, 1. Currently, if you have some numeric data and do a math evaluation, for instance

60 + 220 = 280

If you do a new evaluation on that line, the result is 60 + 220 = 280 standard_in) 1: parse error

SUGGESTION to the math maintainer: Might you alter the code to delete the contents of the line or selection subsequent to an "=" character, before evaluating?

2. The currency math commands, would it make sense to use the detected prefix?

i.e., currently "$20 + $40" evaluates to "$20 + $40 = 60"

Perhaps it should evaluate to "$20 + $40 = $60"

Cheers, Tim
