Today the 6th of May, in Miss Goslin math group had to do a brain teaser, the brain teaser is were we had to count how much marbles there are. The stratigy what me and my budy used was we put ten marbles in first then he put twenty witch equals thirty then he added thirty witch equals sixty after that he added forty witch equals one hundred. So the answer is one hundred. Hope you comment and give me some feedback.
