Answer:
a)8 b)-7 c)-7 d)11 e)3 f)51
Step-by-step explanation:
For all of these problems all we have to do is determine which signs we're using. If we have two negatives, it makes a positive. If we have a negative and a positive, it forms a negative sign.
A) -4 is negative and we have no signs in front so it just stays the same for now. +(+10) will be positive 10. So, -4+10=6 +(+4)=10
Now, we have +(-2) and that would be minus 2. So, 10-2=8
Make sure to add/subtract from left to right
b)5-8+3-7=-7
c)-19+14+21-23
-19+14=-5
-5+21=16
16-23=-7
d)5+10-4=11
e)-3+3+3=3
f)26+32-15+8=51
