Bonjour,
A= 8 - 3 * (-10) = 8 - (3 * (-10) ) = 8 - (-30) = 8 + 30 = 38
B= (8-3) * (-10) = 5 * (-10) = -50
C= [2-7 * (3+2)] - 12 = [2-7*5] -12 = [ 2- 35] -12 = -33 -12 = -45
[tex]D= \frac{5-4*2}{3-5} =\frac{5-8}{3-5} =\frac{-3}{-2} =\frac{3}{2} \\\\E= \frac{-4 * 3}{-8+2} =\frac{-12}{-8+2} = \frac{-12}{-6} = \frac{12}{6} = 2[/tex]
