How do I get the calculator to print the totals? It totals without print but not when I set it to print. Is there a memory clear rather than the CE/C button? When I type 5+5 it prints out 1% or 5++ It seems like the equals doesn't print when adding and when multiplying it prints correctly on the screen but comes up with a print out of a diamond% a 5% and a 2.0*
