7+7=2
8+8=4
we get
7=1,8=2 so we get a series like
1=-5,2=-4,3=-3,4=-2,5=-1,6=0,7=1,8=2,9=3,10=4 and 11=5 and so on
8+5=2+(-1)=2-1=1
10+11=4+5=9
so
4+9=3+(-2)
=3-2=1
8+8=4
we get
7=1,8=2 so we get a series like
1=-5,2=-4,3=-3,4=-2,5=-1,6=0,7=1,8=2,9=3,10=4 and 11=5 and so on
8+5=2+(-1)=2-1=1
10+11=4+5=9
