Think about this. When you add 2 single digit decimal numbers example 8 and 7. Are you able to get a single-digit decimal number sum? You will get 8+7=15. The digit "1" on the left is normally called "carry".
It is the same with binary. Adding 2 bit binary numbers would also yield a 3 bit answer. The Most significant bit (3rd bit) is usually called the "carry" bit.
If you google for the word "binary adder", you'll find there are half adders and full adders. Try to study them and read what they are.
