i mean it s a "brain easer" problem there is need to be easy way
how did you calculated this ?
-1+2^1/2-3^1/2+4^1/2-5^1/2............+2014^1/2 up to ^2
it will be -1+2-3+4-5......-2013+2014=x^2
x^2=1
x=1
cool :)
8080*1514 = 12233120 - the score all of the students exept Payton s
P- Payton
(12233120+P)/1515=8181
8181*1515-12233120 = 161095
i think the answer is: 161095
