let me guess....polish notation? :)
I had to go look up Polish notations. The class I took was Contemporary Mathematics. It’s pretty much math for real life. The class touched on interest rates, loan payments, compounding interest, basic statistics, apportionment, set theory, means, modes, etc. I understood all that.
Jonty30, I absolutely agree about learning how to do the math before using a calculator. I had never touched a TI-84. I didn’t know how to turn the darn thing off. That was much easier to learn for me, than the necessary math for some of the kids. They could enter the numbers, but didn’t know how they were related.
