Answer 1

Respuesta:

$a)60 + ((4 + 3) - 7) - 57 \\ 60 + (7 - 7) - 57 \\ 60 - 57 = 3 \\ b)500 - (6 + (5 - (8 - 7) + (4 + 3) - 2)) \\ 500 - (6 + (5 - 1 + 7) - 2) \\ 500 - (6 + 11 - 2) \\ 500 - 15 = 485 \\ c)856 + (19 - 3 - (6 + (5 - 3) - \\ (2 + 1) + (5 - 3))) - 864 \\ 856 + (19 - 3 - (6 + 2 - 3 + 2) - 864 \\ 856 + (1 9 - 3 - 7) - 864 \\ 856 + 9 - 864 \\ 865 - 864 = 1$

$d) 256-[(5+3)-(4-2)+3]+ \\ {15-[(7+4)- (13-10)]}-234 \\ 256 - (8 - 2 + 3) + (15 - (11 - 3) - 234 \\ 256 - 9 + (15 - 8) - 234 \\ 256 - 9 + 7 - 234 \\ 263 - 243 = 20 \\ e)7 + (10 - (5 - (6 + 4))) - (15 + (4 - 3) \\ + (18 - 2)) - 29 \\ 7 + (10 - (5 - 10)) - (15 + 1 + 16) - 29 \\ 7 + (10 + 5) - 32 - 29 \\ 7 + 15 - 61 \\ 22 - 61 = - 39$
