A=15-[3x(-9-1)]-1+7x0,5
A=15-[3x(-10)]-1+3.5
A=15-[-30]-1+3.5
A=15+30-1+3.5
A=44+3.5 = 47.5
B=[45-5x(4-0,2)]x(-6)
B=[45-5x(3.8)]x(-6)
B=[45-19]x(-6)
B=[26]x(-6)
B= - 156
lPour cet exercice il manque des signes et que signifie le symbole ^ ?
C=120-8[(-10)^+(6-11)((-3+4x5)]

A=15-[3x(-9-1)]-1+7x0,5 = 15 - [3 x -10) ] -1 + 3.5 = 15 - (-30) +2.5 = 15+30+2.5 = 47.5
B=[45-5x(4-0,2)]x(-6) = (45 -5x 3.8) x -6 =( 45 - 19) x 6 = 26 x 6 = 156
C=120-8[(-10)^+(6-11)((-3+4x5)]
= le 10 est puissance quoi ?
