A radio show plays for 3 hours a day. They split their show into talking segments, ad breaks and songs. Talking segments last 10 minutes each, ad breaks last 5 minutes each and songs are played throughout the rest of the show. If the radio show includes 3 talking segments and 5 ad breaks in today’s show, how long, in minutes, does the show play songs?
The entire radio show plays for 3 hours * 60 minutes = 
<gadget id="calculator">3*60</gadget>
<output>180</output>
180 minutes.
The talking segments use 3 talking segments * 10 minutes per talking segment = 
<gadget id="calculator">3*10</gadget>
<output>30</output>
30 minutes each.
The ad breaks use 5 ad breaks * 5 minutes per ad break = 
<gadget id="calculator">5*5</gadget>
<output>25</output>
25 minutes.
In total, the talking segments and ad breaks use 30+ 25 = 
<gadget id="calculator">30+25</gadget>
<output>55</output>
55 minutes.
This leaves 180 - 55 = 
<gadget id="calculator">180-55</gadget>
<output>125</output>
125 minutes for the radio show to play songs.
