What is the carry rule for base r?

R is actually an integer, which is commonly used such as R=2 (binary), R=8 (octal), R=16 (hexadecimal), and more A wide range of R can be any positive integer, which means that the base number advances by 1 when R occurs. Only the numbers 0~R-1 appear in the number, and R cannot appear. For example, when binary numbers advance by 1 when encountering 2, 2 will never appear; octal system Every 8 in a number advances to 1, and 8 never appears; in a hexadecimal number, every 16 advances to 1, and from 0 to F represents 0 to 15, there is never a 16; the more common decimal numbers we usually use advance to 1 every 10.

The R base system means that every R is advanced by 1, which means that R can be advanced one place. For example, the base system we often use is the decimal system, which is that every 10 is advanced by 1.

Example: 3 4=7, if there is no carry if it is not enough to 10, it is equal to 7.

27 45=72

First of all, 7 5 = 12>10, move one digit to the left, and all tens digits will be available, 2 4 1 (the 1 just entered) = 7 , the result is 72. Another example is the octal system, which advances 1 every 8.

3 4=7, 27 45=?

First: 7 5=8 4=14, 2 4 1 (the 1 just entered)=7, the result is: 27 45=74
