If $n$ $n$ is "a number", then it's $n - 4^{3}$ $n - 4^3$ .

Explanation:

No real explanation here, just the fact that referring, arbitrarily, to "a number" signals the usage of a variable, that is represented by a letter. "minus the cube of four" can be interpreted as either $- 4^{3}$ $-4^3$ or $- 64$ $-64$ , although since we need our algebraic interpretation to be as close as possible to the description, it's more accurate to write $- 4^{3}$ $-4^3$ .
