TI-58/TI-59 Week: Adding Machine
Introduction
Turn your TI-58 and TI-59 into an adding machine, which uses register R00 as the accumulator.
The soft keys do the following functions:
[ A ]: Clear the accumulator
[ B ]: Add [ + ]
[ +/- ] B: Subtract [ - ]
[ C ]: Multiply [ × ]
[ 1/x ] [ C ]: Divide [ ÷ ]
[ D ]: Add %
[ E ]: Recall the accumulator
