The math teachers who hate calculators the most don't know how to use them and assume it's easy. "it just adds and reduces the fractions for them"
but they don't know how to make it do that.
It will solve a system of equations too... but you need to know how to put it in standard form and understand the result which is basically a reduced matrix.
I think I'll be doing a calculator workshop FOR TEACHERS next. LOL.
