Binary Addition
Binary is being able to add two numbers together but represent the numbers in binary form, which consist of 1s and 0s
There are for possibilities when adding binary numbers, these possibilities are:
a total of 0 (0+0) put down 0 a total of 1 (1+0, 0+1 or 0+0+carried 1) put down 1 a total of 2 (1+1) put down 0, carry 1 a total of 3 (1+1+ carried 1) put down 1, carry 1
For example, solve 6+7 using binary addition:
First convert 6 and 7 from denary to binary using your preferred method
6 = 4+2+0 = 110 7 = 4+2+1 = 111
Then add them keeping in mind the 4 possibilities
110 +
111
0+1 = 1 1+1 = 0 carry 1 1+1+ carried 1 = 1 carry 1 1 + 0 = 1
so 110+111 = 1101. Converting this number back to denary gives us an answer of 13.
