Carry addition, one of mathematical operations, one of addition. For example, in decimal system, if the number of digits on one digit adds up to ten, then write the number of digits added up on this digit and input the number on the tenth digit to the next digit.

33+ 18=5 1, carry and add (one digit decimal)
5 1- 18=33, abdication minus (if one digit is not enough, ten digits minus one).
Extended data:
A mathematical operation, an addition. When two numbers are added, every time the result of a certain bit is greater than or equal to 10, you need to count 1 to the next bit, which is the carry. For example:
48
+ 56
————
= 104
8+6 = 14 & gt; 10 rises by one place (ten places) to 1.
4+5 plus rounded 1, that is, 4+5+ 1= 10 also needs to be rounded up by one bit (ten bits) to 1.
When there is carry addition in the operation, it is called "carry addition".
