* Temperature Conversion (solving equations)
Conversion from Celsius to Fahrenheit involves multiplication by 1.8
and the addition of 32 as shown below.

eq := f = 1.8 c + 32

Solving for Celsius from Fahrenheit is then.

ceq := solve(eq, c) =>

So, if we know that water boils at 100\deg Celsius, we can find the
boiling point of water in Fahrenheit.

subst(eq, c, 100) =>

Or if we know that paper burns at 451\deg Fahrenheit, we can find the
burning point of paper in Celsius.

subst(ceq, f, 451) =>
