UN POCO DE TEORÍA: VER CARPETA

1.- Realiza las siguientes restas

a) (+5) – (-8) = ______________
b) (-25) – (+4) =____________________________________
c) (+7) – (+12) = ____________________________________
d) (-10) – (-7) = _____________________________________
e) (-2) – (-9) = ______________________________________
f) (-4)– (+8) – (+13) – (-11) = __________________________

2.- Resuelve

a) (15-11) + (3-7) = _______________________________________________________
b) (-3 + 8) + (1 – 10) – (-5 + 9) =_______________________________________________
c) – 7 – 5 – 3 – (+8 + 6 – 4) = __________________________________________________
d) – 22 – 25 + (-3 + 10 + 3) – (-2 + 11 + 20) =____________________________________
________________________________________________________________________________

3.- Calcula

a) -3 + 8 + 10 – 1 = ______________________________________________________________________________________________________________________________
b) – 1 +3 – 4 + 25 = _____________________________________________________________________________________________________________________________
c) 15 + 20 – 12 + 3 = _______________________________________________________
________________________________________________________________________
d) 4 – 3 + 16 – 2 =_______________________________________________________
________________________________________________________________________
e) – 5 + 10 – 6 + 5 = _________________________________________________________________________________________________________________________________
f) 7 – 6 + 1 – 14 + 13 = _________________________________________________________________________________________________________________________________
