I=12+8-4+16.
=20-4+16
=16+16
=32
coucou,
I = 12+ 8-4 +16
= 12+4+16
= 16 + 16
J=10× 8÷4 ×5
= 10×2×5
=20×5
= 100
K=8+9-5,7-4,7
=8+3,3-4,7
= 11,3-4,7
=6,6
L= 3-2,7 + 2,3+4
= 0,3 + 6,3
M=25-7-4 +6
= 18-4 +6
= 14+6
= 20
N= 20×12÷6÷2
= (240÷6) ÷2
= 40÷2
=20
P=55-7×4+6
= 55 - (7×4)+6
= (55-28)+6
=27+6
=33
Q=12×6÷4-1
=12×(6÷4)-1
= (12×1,5)-1
= 18-1
=17
