If you are not familiar with mathematical formulae, they can appear very confusing! This page is intended to help you with the various formulae used in the IRC Rule:
* Multiply
< less than
> greater than
^2 squared (eg. 4^2 = 4 squared = 4 x 4)
^3 cubed (eg. 9.5^3 - 9.5 cubed = 9.5 x 9.5 x 9.5)
^0.5 square root (eg. 25^0.5 = square root of 25 = 5)
m^2 square metres
( ) calculations shown iithin brackets are solved first eg. 4*(3+3) = 4*6 = 24
