In elementary arithmetic a carry is a digit that is transferred from one column of digits to another column of more significant digits during a calculation algorithm. When used in subtraction the operation is called a borrow. It is a central part of traditional mathematics, but is often omitted from curricula based on reform mathematics, which do not emphasize any specific method to find a correct answer.

Famous quotes containing the word carry:
“It is a very true and expressive phrase, He looked daggers at me, for the first pattern and prototype of all daggers must have been a glance of the eye.... It is wonderful how we get about the streets without being wounded by these delicate and glancing weapons, a man can so nimbly whip out his rapier, or without being noticed carry it unsheathed. Yet it is rare that one gets seriously looked at.”
—Henry David Thoreau (18171862)
