1. The problem statement, all variables and given/known data For all real numbers x and y, ceiling of x,y = ceiling of x times ceiling of y For all odd integers n, ceiling of n/2 = (n+1)/2 2. Relevant equations definition floor: floor of x = n n<or equal to x < n+1 definition ceiling: ceiling of x=n n-1 < x <orequal to n. 3. The attempt at a solution No idea where to even start. I don'r quite understand the concept and floor & ceiling.
