%28a%2F-25%29%2B3%29 < 3 [isolate the a-term]
.
%28a%2F-25%29%2B3-3%29 < 3-3
.
a%2F-25%29 < 0
.
%28-25%2F1%29%28a%2F-25%29 > %28%28-25%2F1%29%280%29%29
[flip the sign when multiplying or dividing by a negative number]
.
a>0
.
<______(-1)________(0=====> infinity)
[On the number line, "a" is greater than (0)]
.
Therefore, "a" is greater than every number after zero (but does not include zero) on to infinity]
.
(0, infinity) [use parenthesis to indicated that the number is not included]
