-10^2 (OT)

[michael j. foy]

Dar is right, go to the head of the class, now where is my had with the
big D on it :-)

it's bodmas isn't it
Brackets
Of (as in powers of)
Division/multiplication whichever is encountered first, but it's
commutative so it doesn't matter
Addition/Substraction of equal importance
So in -10^2, the power is competed first then the negation is then
applied

I believe in traditional mathematical notation negation is like 
multiplication of -1.  Since the power would be done before 
multiplication, the traditional view would see the expression as 
-(10^2).
