What is the 1 that is carried called?

These are all Latin, would this make sense?

The Latin word for "carry" is "porto", would it be called Porto?

Just guessing here

Example:

  123  <-- Augend or Addend  +  9  <-- Addend ______      1   <-- What is this called?   123  +  9 ______     2     123  +  9 ______   132  <-- Sum

In compsci, when we add binary numbers, we call this the "carry bit."
