1. Resuelve las siguientes operaciones:
1 + 5 + (-2) + (-3) = [1]
2 + (-2) + 1 + (-6) = [-5]
5 + 8 + (-2) + (-1) = [10]
8 + (-1) + 9 + (-5) = [11]
7 + 6 + (-8) + 9 = [14]
9 + (-8) + 9 + (-8) = [2]
6 + 9 + (-4) + (-1) = [10]
5 + 3 + (-7) + (-6) = [-5]
4 + (-1) + 4 + (-2) = [5]
2 + (-9) + (-2) + 8 = [-1]
{[2+3] – [(-1)+ (-2)] -2} = [0]
2. MULTIPLICA
a) 3 • (-5) =
b) (-6) • (+4) =
c) (-3) • (+6) =
d) 8 • (+2) =
e) 10 • (-1) =
f) (-2) • (-4) =
G) {(-2). (+2)- [(-2). (-1)]} =
e precio-costo y valor?
