Answer: -11
Step-by-step explanation:
+(-8) can be simplified to -8 because when you multiply a positive sign by a negative sign, the outcome is a negative sign. So your problem is -3-8= and the answer is -11 because when two numbers with the same sign are subtracted/added by each other, the numbers just get added and the sign stays the same. If you're still confused, use a number line. Hope this helps!
(13 + 14) + 11 = 13 + (14 + 11) --- associative property
13 + 14 + 11 = 11 + 14 + 13 -- commutative property
