Problem 1:
-27+(-5)+27
-27 and 27 cancel out leaving you with -5 as the answer.
Problem 2:
6*5(1/5)
start by multiplying 5 and (1/5) which gives you 1.
6*1=6
Problem 3:
%281%2F4%29-8%283%2F4%29
this is the same as
-8%28%283%2F4%29-%281%2F4%29%29
which gives you -8 (1/2)
Problem 4:
5-2(2(1/2)+3)
start by doing what is in the ( )
2%281%2F2%29%2B3=5%281%2F2%29
now multiply that by -2
-2%2A5%281%2F2%29=-11
now the equation is 5-(-11)
the 2 negative signs turn into 1 postive sign
5+11=16
