sqrt(x) - square root
floor(x) - round down ie: floor(1.6) = 1
ceil(x) - round down up ie: ceil(1.2) = 2
min(x, y) - will return the minimum of the two values ie: min(1, 2) = 1
max(x, y) - will return the maximum of the two values ie: max(1, 2) = 2
round(x) - will round the number to the nearest whole ie: round(1.2) = 1 and round(1.5) = 2
