[3 ( 4 - 2 ) + 12] + [ ( 5 X 4 ÷ 2 ) + ( 20 ÷ 4 X 3) ]?
[3 ( 4 - 2 ) + 12] + [ ( 5 X 4 ÷ 2 ) + ( 20 ÷ 4 X 3) ].
[3 ( 4 - 2 ) + 12] + [ ( 5 X 4 ÷ 2 ) + ( 20 ÷ 4 X 3) ].
En resumen
[3(4 - 2) + 12] + [(5×4÷2) + (20÷4×3)] = [3. 2 + 12] + [(20÷2) + (5×3)] = [6 + 12] + [10 + 15] = 18 + 25 = 43.
[3(4 - 2) + 12] + [(5×4÷2) + (20÷4×3)] =
[3.
2 + 12] + [(20÷2) + (5×3)] =
[6 + 12] + [10 + 15] =
18 + 25 = 43.
