말뭉치

1. When kids are learning two-digit addition and subtraction, one of the concepts they'll encounter is regrouping, which is also known as borrowing and carrying, carry-over, or column math.
2. Before tackling carry-over math, it's important to know about place value, sometimes called base-10.
3. Addition is where the carry-over principle of math comes into play.
4. In elementary arithmetic, a carry is a digit that is transferred from one column of digits to another column of more significant digits.
5. Traditionally, carry is taught in the addition of multi-digit numbers in the 2nd or late first year of elementary school.
6. The same carry bit is also generally used to indicate borrows in subtraction, though the bit's meaning is inverted due to the effects of two's complement arithmetic.
7. Normally, a carry bit value of "1" signifies that an addition overflowed the ALU, and must be accounted for when adding data words of lengths greater than that of the CPU.
8. So what we do is we write the 6 in the 1's place and we carry the 1.
9. If it's a two-digit answer you carry the left most digit up to the next column.
10. I would carry it.
11. But there's no where to carry it to, so I write it down just like that.
12. When we learned about addition, we used the term carry.
13. To be honest, we prefer the term carry, but you need to say the word your teacher wants to hear.
14. For example: in decimal addition, if you add 8 + 2 you get ten, which you write as 10; in the sum this gives a digit 0 and a carry of 1.
15. Adding 0 and 1, we get 1 (no carry).
16. ) we can write out the calculation (the results of any carry is shown along the top row, in italics).
17. In this case the extra carry from the most significant bit has no meaning.
