Its just a mistake in understanding. Looks like it meant how many 40+40's are there, instead of actually multiplying the amount before.

It's not a "mistake in understanding". It's the order of operations.

First comes grouping symbols, like parentheses, fraction bars, etc.

Next is exponents.

Then multiplication and division (left to right)

And after that, addition and subtraction (left to right)

The answer is 41, because you need to follow the above order to complete mathematical equations.

TL;DR - You always multiply before you add, so the answer is 41.

what does the p.e. mean? i know it as b.i.r.d.m.a.s. from the uk/ireland

P is for parentheses, and e is for exponent. that's how they teach us in america.

i dont actually know what either of those mean, despite the fact i am studying maths in uni haha
brackets, indicies, roots, division etc was my way!

I learned b.e.d.m.a.s
brackets, exponents, division, mulitplication, add, subtract

What does b.i.r.d.m.a.s. stand for?

What if you add the 1 and 0 together FIRST,then add 40 to 40 then mutlyply that by 1.
That would be 80.

Order of operations numb nuts, you can't chose which to do 1st, that was universally decided long ago
