I hate calculators, because they weaken our skills. They are great for speeding up things, but horrible for increasing our math skills.
If it were up to me, calculators would be banned until college, to which you’d then take a first semester course on how to use one.
I think you should have to know how to do everything with a pencil, sheet of paper, and the appropriate charts.
Bump and repeat!
Parent should tell their kids to learn the first universal language: mathematics. Learn your native language. Learn to write well in it. Then ace math in high school and onward; learn the hard sciences; and study some form of engineering and you can do anything you want in life.
I agree completely. I have fond memories of setting up a problem in calculus and graphing it by finding the intercepts and where it was increasing or decreasing. It really helped visualize the equation.
