2 + 3 + 4 + 5 + 6 = 20
3 + 6 + 9 + 22 + 28 + 1 + 6 + 5 = 80
57+97+37+47+6 = 244
I meant 6 4 over 5 plus 3 3 over 5
-3
4 + 6 + 6 + 5 + 5 + 4 + 6 + 5 + 5 + 6 + 5 + 5 + 5 + 3 = 70
170 divided by 5 plus 378 divided by 6 = 97
2.5+3+5+5+6=21.5
It is: -5+(-6)+3 = -8
3 + 5 + 9 + 5 + 5 + 5 + 5 + 6 + 4 = 37
2200x0+11 ---- 3+3 = 6 6+5 = 11
6 + 5 + 3 + 2 + 9 = 25
2 + 3 + 4 + 5 + 6 = 20
7 + 5 + 4 + 5 + 3 + 4 + 6 + 5 + 4 + 5 + 6 + 4 + 7 = 65
3 + 6 + 9 + 22 + 28 + 1 + 6 + 5 = 80
It is: 7+6+5+4+3 = 25
-6 + (-3) + 4 = -5
