A = 7+3×5 = 7 + 15 = 22
B = 5 x 2² - 6 = 5*4 - 6 = 20 - 6 = 14
C = 4 × 7 +18 ÷2
= 28 + 9 = 37
D = ( 5 + 3 ³ ) / 4 = ( 5 + 27 ) / 4 = 32 /4 = 8
E= 12 ÷ 4 + 7 × (5-2)
= 3 + 7 * 3 = 3 + 21 = 24
F = 14+ 24 ÷ [(9-7) + 2×3]
G = [(12 -3) × (37-9×3)+2] ÷4
= [9 x ( 37 - 27 ) ] : 4
= ( 9 x 10 ) : 4
= 90/4
= 22.5
