Bonsoir
B:6*[13-(5-2)] = 6*[13-3]
= 6 * 10
= 60
C:[(8-2)*8]/4+8 = [6*8]/4+8
= 48/4 + 8
= 12 + 8
= 20
D: [(31-5)-2*7)]/(6/2) = [26 - 14] / 3
= 12/3
= 4
E: 3.4+[9*(8/2)]/6*7+2.6 = 3,4+[9*4]/6*7+2,6
= 3,4+36/6*7+2,6
= 3,4+6*7+2,6
= 3,4+42+2,6
= 48
F: 21+8*2[2+(13-9)*3]-(10-6) = 21+8*2[2+4*3]-4
= 21+16(2+12)-4
= 21+16*14-4
= 21+224-4
= 241 -
