If you are not familiar with mathematical formulae, this page will help explain 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 within brackets are solved first eg. 4*(3+3) = 4*6 = 24
