aminooo Posted March 26, 2011 Author Share Posted March 26, 2011 Hey, this game requires some nice knowledge of mathematics.It's pretty simple, someone starts by posting an equation, a sequence, or even a number.The next one should guess it, then he posts an another one, and going on.I'll start :p1,2,3,5,8,13,21,34,55,89,144,233,377,610,987,1597… Link to comment Share on other sites More sharing options...

Lavos Posted March 27, 2011 Share Posted March 27, 2011 dont ask me why, but after 30 mins of looking at this I thought this was fucking genius! Nice work Mr.Sean Link to comment Share on other sites More sharing options...

SidneyHarrington Posted April 1, 2011 Share Posted April 1, 2011 Math games are great for 2 reasons1) They make math seem like a "fun," worthwhile endeavor.2) They can do the drill and kill for basic math facts, which is whatstudents need most in early grades.

river00 Posted June 25, 2011 Share Posted June 25, 2011 I'll put in the question since no one put in one.A trough is 12 feet long and 3 feet across the top (see figure). Its ends are isoceles triangles with altitudes of 3 feet.a. If water is being pumped into the trough at 2 cubic feet per minute, how fast is the water level rising when it is 1 foot deep?b. If the water level is rising at a rate of 3/8 inch per minute when h = 2, determine the rate at which water is being pumped into the trough.
