We require a mnemonic to remember e whenever we scribble math. To express e, remember to memorize a sentence to simplify this

e = 2.7182818284

Mnemonic Device

2 = We 7 = require 1 = a 8 = mnemonic 2 = to 8 = remember 1 = e 8 = whenever 2 = we 8 = scribble 4 = math

Variation

To express e, remember to memorize a sentence to simplify this.

Explanation

The lengths of the words, in both sentences, constitute the number 2.7182818284 e. This number is the base for natural logarithms.
