Topic: composite functions. Examples: addition, multiplication, subtraction.

s(x) is defined as x^2;
t(x) is defined as 5x^3.

To create (t + s)(x), just add s(x) and t(x) together.

To create (t * s), multiply s(x) and t(x) together.

To creaste (t - s)(2), first write t(x), subtract s(x) from it, simplify, and then let x=2.
