Sagot :
B=(22-14) : 2+2 x [26-2x (7-4+6 -1 + 5)]
= (22-14) : 2+2 x [26-2x(7+6+5 -4-1)]
= (22-14) : 2+2 x [26-2x(18 -5)]
= (22-14) : 2+2 x [26-2x13]
= (22-14) : 2+2 x [26-26]
= 8 : 2+2 x 0
= 4+0 = 4
B= (22-14) : 2+2 x [26-2 x (7 -4 +6 -1 +5)]
= 8 : 2+2 x [26 -2 x 13]
= 8 : 2+2 x [26-26]
= 8 : 2+2 x 0
= 4 + 0
= 4
