# Newly Defined Functions

Sometimes if we are going to use a particular set of operations frequently, it can be useful to give that set of operations an abbreviated symbol to stand for the whole.

For example, if we define $$\uparrow$$ to mean $$\uparrow x = x^2 + 1$$, then what is the value of $$\uparrow 10 + \uparrow 3$$?

Given the definition, $$\uparrow 10 + \uparrow 3 = ((10)^2 + 1) + ((3^2) + 1 ) = 111$$.
