2+ (2-3) / 7(3+9) 2+(-1)/7(12) = 1/84 or .012 if you meant to multiply the WHOLE equation by 7 it would be: 7[2+(2-3)/(3+9)] 7[2+(-1)/(12)] 7(1/12)= 7/12 or .583

1+2+3+4+5+6+7+8+9=37
7-4=3
7 1/4 :)
(7-3)^2 plus (7-1)^2 = 16+36
3 + 3 - 7 + 2 - 1 + 109 = 109
2+ (2-3) / 7(3+9) 2+(-1)/7(12) = 1/84 or .012 if you meant to multiply the WHOLE equation by 7 it would be: 7[2+(2-3)/(3+9)] 7[2+(-1)/(12)] 7(1/12)= 7/12 or .583
((2 plus (1 over 4)) plus 3) plus (7 over 8) = 6.12500
1 + 1 + 2 + 3 + 4 + 5 + 6 + 7 + 8 + 9 = 46
3n+1=7 3*2+1=7

9+8--2+3 9+8-1 (-2+3 is 1) 9+7 (8-1 is 7) therefore the answer is... 16
it is 2 cause 6-7 is -1+3=2 6 - 7 + (-3) = -1 - 3 = -4
1+2+3+4+5+6+7+8+9=37
1/7 + 2/3 is 17/21
6/7
