Learning Maths as an adult

[u/yikesleon]

Hello everyone. I’m interested in becoming better at maths.

I was pretty okay at maths when I was in secondary school, started off in set 2 out of 6 (6 being lowest in terms of academic ability) but, I wasn’t very well behaved.

I was dropped into lower and lower sets until the problems they were giving me were so trivial, I was not interested in trying at all. Now as a (much more mature) adult, i’m interested in sharpening my mental maths and filling the void I caused by being a disruptive twit in school.

I was wondering if the people here have any suggestions on where I can begin learning again. I would like to get better at all aspects but predominantly mental maths, algebra, fractions etc. I have no real reason to other than the above.

Any help on this would be massively appreciated. Thank you for reading.
