Answer:
a. -3
b. -4
c. -1
d. -1
e. -5
Step-by-step explanation:
a. 3 + (-6) or 3 - 6 = -3
b. 5 + (-9) or 5 - 9 = -4
c. 7 + (-8) or 7 - 8 = -1
d. (-5) + 4 or -5 + 4 or +4 - 5 or 4= -1
e. (-8) + 3 or -8 + 3 or 3 - 8 = -5
note:
plus sign is optional, so it can be invisible or not.
shortcut for me:
inversely
a. 6-3= 3 but I put a negative sign before the answer, so it could be -3.
b. 9-5= 4, and change it as negative four (-4).
c. 8-7= 1, then -1.
d. 5-4= 1, then -1.
e. 8-3= 5, then -5.
if you are confused to solve by your own, you should always use a scientific calculator.
