## Number Anagrams

To do: Add some number anagrams.

## 2

Two (2) is the only prime number whose English name does not end in “e” or “n”.

## 370

\(370 = 3^3 + 7^3 + 0^3\) — 370 is a narcissistic number.

## 2187

\(2187 = 3^7\)

\(2187 = 10000000_3 \textrm{ (10,000,000 base 3)}\)

\(2187 + 1234 = 3421\)

\(2187 + 12345 = 14532\)

\(2187 + 123456 = 125643\)

\(2187 + 1234567 = 1236754\)

\(2187 + 12345678 = 12347865\)

\(2187 + 123456789 = 123458976\)

The sums on the right are anagrams of the numbers added to \(2187\).

\(2187 + 123 = 2310\) sort of fits this pattern.

\(2-1-8+7 = 0\)

\(2+1+8+7 = 18 \rightarrow 1+8 = 9\) — 2187 is divisible by 9.

\(2187\) is a Lucky number.

### 2187 Anagrams

Exchange the last two digits of \(2187\) to make \(2178\), multiply by \(4\), and you get \(8712\), the second number backward.

Take \(2187\) from \(9999\) and the result is \(7812\), its reversal.

Multiplying \(21\) by \(87\) produces \(1827\).

The first four digits of the constant \(e\) are \(2.718\).

The number of cubic inches in a cubic foot (\(12^3\)) is \(1728.\)
