Suprimir paréntesis, corchetes y llaves y resolver 1) 5 + 4 - (3 + 1) = 2) 4 + [10 - (5 - 1)] = 3) (27 + 5) - (30 - 2) = 4) 78 - {[4 + (5 - 1)} - 2 =.

En resumen

1) 5 + 4 - (3 + 1) = 5 + 4 - 3 - 1 = 5 2) 4 + [10 - (5 - 1)] = 4 + (10 - 5 + 1) = 4 + (6) = 4 + 6 = 10 3) (27 + 5) - (30 - 2) = (32) - (28) = 4 4)78 - {[4 + (5 - 1)} - 2 = 78 - (4 + (4)) - 2 = 78 - (4 + 4) - 2 = 78 - (8) - 2 = 78 - 8 - 2 = 68.

1) 5 + 4 - (3 + 1) =

5 + 4 - 3 - 1 = 5

2) 4 + [10 - (5 - 1)] =

4 + (10 - 5 + 1) =

4 + (6) =

4 + 6 = 10

3) (27 + 5) - (30 - 2) =

(32) - (28) = 4

4)78 - {[4 + (5 - 1)} - 2 =

78 - (4 + (4)) - 2 =

78 - (4 + 4) - 2 =

78 - (8) - 2 =

78 - 8 - 2 = 68.
