Programming… again??!!

Day 3 – I’ve encountered the biggest block in my endeavor to understand how my HP12c works – programming.

There are lines and lines one has to understand and a way to program instructions into the calculator. I’ve skipped this section, saw some complex mortgage calculation, then lo-and-behold, you have to understand programming to do it. So back to page 129 of my user manual…..
