Nope, completely lost me there. I spent my maths GCSE sitting at the back of class with a box of coloured counters. Seriously, they had no idea what to do with me so they made me play with blocks. At the age of 15. Unbelievable...

2^3 = 2*2*2 = 8
4^2 = 4*4 = 16
4^5 = 4*4*4*4*4 = 1024
How about that????? Alright, I giveup. I feel sorry for you.
You should change it to
L/10+(1+T/100)*P^0.3
No way of misinterpreting that.
Edit: now with even less brackets
L/10+(1+T/100)*P^0.3

Oh, right. But traditionally, the ^'s are in the front, and anything added or substracted from it, comes last.
The problem with
P^0.3*(1+(T/100))+(L/10)
is that there's no telling whether you multiply the P^0.3 or only the 0.3. It comes down to technical limitations since you can't type the 0.3 in smaller size above the P like a power should be.
Plus the brackets around T/100 are unnecessary since you divide before adding anyway.
It doesn't, ^ connects P and 0.3. Because indices are before multiplication in BIDMAS, you do the indices first and multiply the answer by the rest of the formula.
Using brackets just cleans up the formula and makes it easier for anyone to understand.
No. There's nothing to indicate that only 0.3 is the power (I'm sorry if I'm using the word "power" incorrectly, I'm obviously not familiar with mathematical terms in English)
For all I know, the whole 0.3*(1+(T/100))+(L/10) could be the power.
And unnessecary brackets do nothing but add confusion, but that's not much of a problem.
The bracket separates them..?
You do everything in the brackets before you do anything else.
e.g
3^2* (4+3) ->
3^2*7 ->
9*7 ->
63
I can read that as
3^2*(4+3)=3^2*7=3^14=4782969
Powers are written like this - yeah well that copy-paste didn't work, right so all I'm saying it's a matter of technical limitations, because you can't tell which part is a power for sure.

You were taught maths wrong then. You do everything in brackets before you do anything else. Therefore you always end up with 3^2*7. Then the rules say that indices come next. The 3 is connected to the 2 because the ^ is between them - the 7 doesn't have anything to do with it. Your answer is 9 and are left with 9*7.
