When adding numbers in the binary

**system**it is important to remember that it has only two symbols - 0 and 1. Any other characters to be in it can not. Therefore, the addition of two units 1+1 gives 2 decimal**system**and 10, as 10 is the next unit number in binary**system**.It is necessary to remember simple rules of addition in binary**system**: 0+0 = 0, 1+0 = 0+1 = 1, 1+1 = 10. These rules are necessary to put**the number**in the binary**system**in a column. As can be seen, in the case of adding unit to unit, unit goes to the next digit.It is obvious that adding zero to any binary number will not change that number.2

**number**easy to store in a column. Rules in binary**system**similar to the addition rules of addition in a column in the decimal**system**.Let them add up**the numbers**1111 and 101. Write the number with fewer digits 101 under the number 1111 - figure category one**number**should appear above the figure of the same category of other**numbers**. Now you can add these**numbers**. In the first category of 1+1 gives 10 - write a 0 under the units in the first category. Unit 10 goes into the sum of the digits of the second category. In the second bit 1+0. After adding the units from the first category will get the same 10. The unit goes in the third category and the second category the amount will also be zero. In the third category 1+1+1 (unit moved here!) gives 11. The third digit of the sum will be 1 and the other unit from**the number**11 will move in the fourth degree. The fourth category only has the number 1111. 1+1 = 10. Thus 1111+101 = 10100.3
