All four statements below mean exactly the same thing. Which of the following is the easiest for you to understand?

•  $\left(f\ \ o\ \ g\right)\left(-3\right)$  

•  $f\left(g\left(-3\right)\right)$  

• "f of g of -3"

• substitute -3 into x in function g, then substitute that value into x in function f

• They're all easy for me to understand.
