A = (- 2)³ x 5 + 130
= - 8 x 5 + 130 ordre de priorité x
= - 40 + 130
A = 90
B = u² - 6 pour u = - 3
= (- 3)² - 6
= 9 - 6
B = 3
C = 3 x + 9 pour x = - 2
= 3*(- 2) + 9
= - 6 + 9
C = 3
D = 10³ x 10⁻³
= 10³⁻³
= 10⁰
D = 10⁰ = 1
E = 2/3 + 20/6
= 4/6 + 20/6
= 24/6
E = 4
F = 2(x + y) pour x = - 2 et y = 3
= 2(- 2 + 3)
= 2 * 1
F = 2
G = 1/6 - (1/6 - 4)
= 1/6 - (1/6 - 24/6)
= 1/6 - (- 23/6)
= 1/6 + 23/6
= 24/6
G = 4
H = 5 m² + 5 m + 4 pour m = - 1
= 5*(- 1)² + 5*(-1) + 4
= 5 - 5 + 4
H = 4
I = 1/2 + 1/3 + 1/6
= 3/6 + 2/6 + 1/6
= 6/6
I = 1
J = n - t pour n = 1/3 et t = - 2/3
= 1/3 - (- 2/3)
= 1/3 + 2/3
= 3/3
J = 1
