7/12+4/5= 83/60 or in decimal form it is 1.383333333
7 + 5 + 4 + 5 + 3 + 4 + 6 + 5 + 4 + 5 + 6 + 4 + 7 = 65
16?
1 + 1 + 2 + 3 + 4 + 5 + 6 + 7 + 8 + 9 + 12 + 133 + 4 = 195

Start at -5. Move 7 places to the left (to -12). Move 4 to the right (-8).
-12
-4 + 5 + (-7) = -6
1 + 2 + 3 + 4 + 5 + 6 + 7 + 8 + 9 + 10 + 11 + 12 = 78
