A = - 2 + 7 - 5 - 10 = 5 - 5 - 10 = - 10
B = - 2 + 7 - (5 - 10) = 5 - (-5) = 5 + 5 = 10
C = 20 - 37 + 4² + 6 = - 17 + 16 + 6 = - 1 + 6 = 5
D = 20 - 3 × (7+4)² + 6 = 20 - 3 × (11)² + 6 = 20 - 3 × 121 + 6 = -337
E = -2 × (-2) × (-2)×(-2)×(-2)= ( - 2)⁵= -32
F = 100 - 50 / (-5) = 100 - (-10) = 100 + 10 = 110
G = - 20 + 5 × (-4) - 10×(-2) = -20 - 20 + 20 = - 20
H= ( 5 + 3 × (5 - 20) ) / 5 = ( 5 + 3× (-15))/5 = (5 - 45) / 5 = (-40) / 5 = - 8
I = (6 - 9 ×(-4) )/ ( 2 + 1 - 9) = (6 +36) / (-6) = 42/ (-6) = (-7)
