100 - 5.5 * 2 + 8 * 3 = 100 - 11 + 24 = 89 + 24 = 113.153 * 6.7 * 2 - 9 * 3 = 1025.1 * 2 - 27 = 2050.2 - 27 = 2023.2.
36 * 2 (7.5 * 2 * 8.5 * 2) = 72(15 * 17) = 255 * 72 = 18 360.
Verified answer
Bonsoir,A = 100 - 5,5 x 2 + 8 x 3
A = 100 - 11 + 24
A = 113
B = 153 x 6,7 x 2 - 9 x 3
B = 2050,2 - 27
B = 2023,2
C = 36 x 2(7,5 x 2 x 8,5 x 2)
C = 72 x 15 x 17
C = 18 360
