1.why is +1+1=+2 why cant it be +3
2.Why is +1*-1=-1 why cant it be something else
3.why are the hilly areas more cooler than the ordinary
areas?

Answer Posted / amir sharif

+1+1=2....i dont know the answer
1*-1=-1....i dont know the answer

The hilly areas like ooty and kodaikanal r more cooler
because of the suns reflection, the low lying areas recieve
the suns ray first and afterwards it gets reflected, by the
time the suns ray reaches, it cools down and there is no
heat in the hilly area thats why hilly areas r more cooler
then low lying areas..
