Explicación paso a paso:
i) 5 - ( -10) + 2 j) (-2) + (-3) - 25 2) Calcule o valor das expressões: a) (-3) . (+7) + (-8) . (-3) b) (-3) + (+2 ) - 7 c) 8 + (-3 -1) d) (-2 + 6) : (+3 – 5) e) –(-5) + (-7 + 4)
Respuesta:
5
8 + 4 = [tex]\frac{12}{4}[/tex] (lo divides entre 4) = 3
10 + 6 = [tex]\frac{16}{4}[/tex] (lo divides entre 4) = 4
12 + 8 = [tex]\frac{20}{4}[/tex] (lo divides entre 4) = 5
