Wait, let me just clear up my point. If you can do something then by all means use a calculator to do it. Then to the extent where if I have to solve a really awkward integral I'm just going to use a calculator because I know I am capable of doing it and the time I'd have to spend looking up how to do it isn't worth the time.

Whereas actually understanding how to manipulate simple algebra is a hugely important skill which should be learnt because it's massively +EV and in all honesty most simple algebra would take longer to type into a calculator than solve by hand.

I'm not against someone who can do the algebra using a calculator to simplify 2 lines of algebra, but it's ridiculous to suggest it for something like "F + E(1-F) + (1-F)(1-E)"
