Step-by-step explanation:
Spanish
(a) 9 - 3 = 6
(b) 12 - 13 = -1
(c) -19 + 13 = -6
(d) -12 +19 = 7
(e) 19-12 = 7
(f) 21 - 21 = 0
(g) -38 + 38 = 0
(h) 12 + 13 = 25
i) - 8 + 6 - 1
= -9 + 6 = -3
j) (+8) - (+5)
= 8-5 = 3
k) - 13 + 7 - 2– 8 + 15 - 1
= -13-2-8-1 + 7 + 15
= -23 + 22
= -1
l) - 2 - 4 - 1
= -7
m) (- 8) + (- 5)
= -13
n) + 22 - 3 - 14 - 5 + 24 + 12
= + 22 + 24 + 12 - 3 - 14 - 5
= 58-22
= 36
o) 12 - 7 + 3
= 12 + 3-7
= 15-7
= 8
p) (- 3) + (+ 9)
= -3 + 9
= 9-3
= 6
q) (- 2) - (- 3) + (+ 5)
= -2 + 3 + 5
= 1 + 5
= 6
r) 4 + 13 - 21
= 17-21
= -4
s) (+ 2) + (- 7)
= -7 + 2
= -5
t) (+ 6) + (- 7) - (- 2)
= + 6-7 + 2
= 8-7
= 1
Hay dos reglas a seguir.
1) Los números con el mismo signo (ya sea más o menos) siempre se suman.
2) Los números con los signos opuestos siempre se restan.
Las respuestas se escriben con el signo que estaba con el mayor número en caso de resta.
Las respuestas se escriben con el mismo signo (más o menos) que los números en caso de suma.
Dos números iguales que tienen signos opuestos se cancelan entre sí y la respuesta es cero.
Cuando menos se multiplica por menos, obtenemos un signo más.

There are two rules to follow.
1) The numbers with the same sign ( be it plus or minus) are always added.
2) The numbers with the opposite signs are always subtracted.
The answers are written having the sign that was with the greater number in case of subtraction.
The answers are written having the same sign ( be it plus or minus) as that of the numbers in case of addition.
Two equal numbers having opposite signs cancel eath other and the answer is zero.
When minus is multiplied with a minus we get a plus sign.
