All-binary 1 is the basis of reaching 2, binary and computer system.

The number of n-ary basic data must be less than n.

For example, LZ said all binary 1 is binary, and the basic data is only 0, 1.

Give the calculation formula.

1 1+ 1= 100

If you don't study, eleven plus one equals one hundred. Be careful not to read books.

At first 1+ 1 ends with 2, so it goes to 1 and ends with 0, then the second place is 1, then it goes to 1, then it is full of 2, then it goes to 1, the second place is also 0, and the third place is 0.

N-element calculation method,

Or is it a real example?

10 1

Decimal system is common101(101), and the calculation method is1*102+0 *1+/.

Binary,1* 2 2+0 * 21*1* 2 0 = 4 (corresponding decimal result)

Hexadecimal1*162+0 *1*1*160 = 272 (corresponding to decimal results).

After the decimal point, the exponent is the corresponding negative value (one tenth corresponds to-1, and so on. ).

The basic data of hexadecimal is 0-9, and there are several letters.
