.
<pre>
This absolute value expression to represent the maximum and minimum temperatures inside the oven when the thermostat is set on 400°F  is


      |T - 400| < 15,     (1)


where T is the temperature in the thermostat, when it is set on 400°F.


The inequality (1) has the solutions    {{{T[min]}}} = 385°F <= T <= 415°F = {{{T[max]}}}.
