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.

Ahh, right - I feel all edumacated now. As I told a pupil just last week, if you put rubbish into the calculator you'll get rubbish out. Which he promptly demonstrated!
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 have also had to 'relearn' how to do basic maths with my children.....some of it was very confusing. At my children's primary school they were taught a different way every year group. I studied maths at university level and yet still struggled to understand some of the teaching at this level....which made my kids laugh. I home tutored the middle two from the ages of 14 to 16 and am pleased to say that they both passed their GCSE's so I obviously did something right!
We've been teaching our grandchildren their times tables this weekend through play, which is so much better than formal teaching, but in a school environment there isn't that choice, unfortunately.
As an aside, I'm not sure that the last sentence is punctuationally correct, even after reading it out loud! And I'm sure punctuationally is a made up word
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.
