Is that algebra? I just thought it was arithmetic.
Yes,in its most basic form. It's the "theory" of the maths,how to solve the problem.Where as addition,subtraction and the like are the "actions" used to find the answer. Usually algebra is associated with letters or symbols to represent numbers,just because you have the numbers to start it doesn't alter the thinking. At least that is how it was explained to me in school.

Numerical literacy is a huge thing is all walks of life. Calculus for most, probably not to be honest but as I posted earlier basic maths certainly is the single biggest skill you can learn or teach your kids
See how many threads on here about people not sure how many Amps they need to power their appliances on hols....

I've just compared one of my old calculus textbooks to one my son uses today, so little has changed that I couldn't differentiate between them.

During my 38 years teaching maths, I occasionally made a mistake.This was often brought to my attention by one of the brighter pupils. I would always say " I wondered how long it would take one of you to spot my deliberate mistake , well done".... and next time be more alert "
Usually worked quite well.

As I told a pupil just last week, if you put rubbish into the calculator you'll get rubbish out. Which he promptly demonstrated!
