Billion vs trillion vs quadrillion vs quintillion

Need to know how many zeros a quintillion has?

Simple formula is:

(1000 ^ Modifier) * 1000

e.g. Million has a modifier of 1 => (1000 ^ 1) * 1000 = 1000000

Billion (modifier ‘bi’ => 2) => (1000 ^ 2) * 1000

Trillion (modifier ‘tri’ => 3) => (1000 ^ 3) * 1000

Get it?

Modifiers are:

bi => 2

tri => 3

quadri => 4

quinti => 5

etc…
