I'm not a teacher so hope you don't mind me posting here.
Can anyone tell me at what stage/age-of-child are logarithms taught in UK schools? I understand it might be different between the countries.
The reason I'm asking is long and boring but in a nutshell I don't remember ever coming across logarithms (I didn't take maths further than GCSE) and a friend is telling me it's basic maths I should have covered much younger.
