Rules
An array contains and zero or more entries, which can be either numbers or other arrays

If an array contains exactly one entry, that is the value of the array

If an array is immediately preceeded by a superscript, that is the class of the array. Otherwise, the class is either that of the containing array, if applicable, or else 1. It will always be a nonnegative integer.

$$[a,b,...]=[a\uparrow^{n}b,...]$$, where n is the class of the array and ... represents the rest of the array

An empty array has a value of 1

Example:
$$[2,[^{2}[2,3],7]]$$

$$[2,[2^{2^{2}},7]]$$

$$[2,[16,7]]$$

$$[2,[16^{7}]]$$

$$[2,268435456]$$

$$2^{268435456}$$

Properties
An array of nonzero order whose first entry is 1 will have a value of 1

If the last entry is one, it may be dropped
