(2*4)-(1*8) = 0
A binary number consists of two possible digits: 0 and 1. When using seven digits, each digit can independently be either 0 or 1. Therefore, the total number of binary numbers that can be formed with seven digits is (2^7), which equals 128. Thus, there are 128 different binary numbers that can be written using seven digits.
The greatest 9-digit number using three different digits is 999888777, formed by using the digits 9, 8, and 7 in descending order. The smallest 9-digit number using three different digits is 100000000, created with the digits 1, 0, and 0. This arrangement ensures that the number starts with 1, followed by the zeros to maintain the smallest value.
They work using lots of 0 and 1, and this two digits are the basic digits of binary number system.
It is a system of representing numbers using only the digits 0 and 1, and in which the place values of digits are powers of 2.

Try 130. Or how about 310.

The sum of the digits of the number 10 is calculated by adding its individual digits together. The digits in 10 are 1 and 0. Therefore, the sum is 1 + 0 = 1.
103 and 301
It is 111005 = 77510

The number 0.01010 has four significant digits. The leading zeros (0.01) are not counted as significant, but the digits 1, 0, and the trailing 0 after the last non-zero digit are significant. Therefore, the significant digits are 1, 0, 1, and 0.
