## It's A Big Red Calculator . . .

Our Big Red Calculator is a four-function math calculator with memory, history, percent, plus more, and it's resizable too.

It also remembers its calculations when closed, so when opened again, the calculator is just where the user left off, even if that was in the middle of a calculation.  Nice :-)
