****I don’t recall “e”, Pi, or “i” in Roman numerals.****

numerals = numbers
Should have typed 0 and not zero???????

[where's_the_Outrage?]

They put no bounds on the term “numbers”, as such the dictionary definition should be standard.

num·ber

noun
plural noun: numbers

1. an arithmetical value, expressed by a word, symbol, or figure, representing a particular quantity and used in counting and making calculations and for showing order in a series or for identification.

Integers is not the correct term as they can be positive or negative, plus 0. Whole (Natural) Numbers are probably the best choice as zero is not necessarily included, at least that is what I remember from my college Algebra 3 where we had to prove that Whole numbers are equivalent to Positive or Negative integers, all integers (including negative values) and even by inference equivalent to Rational Numbers.

This is also where I learned that Equals is not the same as Equivalent.
