Question

Calculează:
a) 6+6×( 2+2×3)
b) 3+5× [3+(4+3×2):5]
c) 12×50:[206-(161+4×5)]

Answer 1

a)6+6×(2+2×3)=
=6+6×(2+6)=
=6+6×8=
=6+48=
=54
b)3+5×[3+(4+3×2):5]=
=3+5×[3+(4+6):5]=
=3+5×(3+10:5)=
=3+5×(3+2)=
=3+5×5=
=3+25=
=28
c)12×50:[206-(161+4×5)]=
=12×50:[206-(161+20)]=
=12×50:(206-181)=
=12×50:25=
=12×2=
=24

Answer 2

a) 6+6x(2+6)=
6+6x8=
6+48=
54

b)3+5x[3+(4+3x2):5
3+5x[3+(4+6):5
3+5x3+10:5
3+5x3+2
3+15+2
20

12x50:[206-(161+4x5)]
12x50:[206-(161+20)]
12x50:(206-181)
12x50:25
12x2
