Priority of operatons
This isn't a left-right thing, it's priority of operations. Multiplies are higher priority so you do them first. This lets you write equations like a = 10b + 5c without tons of brackets (brackets say that a part of a formula has to be done first). With brackets the above is 10 + (10 * 0) = 10.

I have NEVER been taught this and I've programmed computers too, and it all worked fine and as expected,
as has it in the physical world, I understand that when brackets are used that means that that part of the equation must be done first, BUT I was never taught that when maths is written in a sentence like that that it is not to be read as a series of instructions, but as a 'math language' which has rules of order of execution regardless of lack of brackets.
This is weird, how can I not have known this till forty fucking three!?
My school teachers must have been shite!

chances are the compiler for your programming language will have taken care of precedence for you?
It's odd for a maths teacher to forgot to teach this...

I can't believe you just tried to correct me on a retro issue.
I'm still right. The Sinclair BASIC language / OS was on an 8K ROM in the ZX81 (4K in the ZX80). Only the RAM size was 1K.

Oh stop it!
I'm still reeling from the sudden knowledge there's a language to math I never knew about till now!
