i know i've only been on for couple of months, but i was always afraid of asking for help. thanks to this site, i now understand all of this theory stuff! ?'s prove that [alpha] + [alpha + 1/3] + [alpha + 2/3] = [3 alpha] for all reals alpha. prove [alpha] + [beta] <= [alpha + beta] alpha/beta are real. i honestly do not know what to do for these, could anyone provide a beacon of light???
