# Modulo

 Note: Historically, the mathematical meaning came before the casual one.
In natural English, the word "modulo" means:
• Correcting or adjusting for something, as by leaving something out of account.
An example is:
• "This proposal is the best so far, modulo the fact that parts of it need modification."
In other words, we talk about something being true modulo something else if the other thing can, or must, be ignored.

In mathematics this term is given a precise meaning, which is discussed more fully on the page about modulo arithmetic.
