The person above answered by converting to decimal. Since our normal algebraic rules are designed for base-10 (ever try dividing in hex?) I suggest using the Calc program in Windows. Start the program, and in View, change the mode to Scientific. You will see one box called "Dec" selected. That is decimal notation. There is Hex for hexadecimal and Bin for binary. Click Bin, type in 1010, click +, type 1101, and press enter. FYI, if you now click Dec you will instantly convert the answer (10111) to decimal (23.)
1010 (eight plus two)
m
100
0111 = decimal 7 0011 = decimal 3 ____ 1010 = decimal 10 ____
It is a symbol representing addition, one of the basic binary operations in arithmetic.
Add in base two arithmetic 1101 + 1110 + 101 =
1010
1010
1010
100001
8+12=1010
The sum would be 12,112
