Something similar happens in

**binary**addition when you**add 1**and**1**; the**result**is two (as always), but since two is written as 10 in**binary**, we get, after summing**1**+**1**in**binary**, a**digit**0 and a carry of**1**.

Keeping this in view, what happens when two binary numbers are added?

When **two numbers are added** together in denary , we take the first **number**, **add** the second **number** to it and get an answer. For example, 1 + 2 = 3. When we **add two binary numbers** together the process is different. 1 + 1 + 1 = 11 (**binary** for 3)

**Binary**Arithmetic

**Binary**digits are added two at a time and any carry must be carried over to the next higher column of digits. To get the

**sum**of three digits, add the first two and then add the

**sum**to the third digit. To add

**large binary numbers**add one column of digits starting with the least significant position.

Considering this, what do the 1 and 0 mean in binary?

**Binary** (or base-2) a numeric system that only uses two digits — **0** and **1**. Computers operate in **binary**, **meaning** they store data and **perform** calculations using only zeros and ones. A single **binary** digit **can** only **represent** True (**1**) or False (**0**) in boolean logic.

**There are 3 basic rules for adding binary numbers:**

- 0 + 0 = 0.
- 0 + 1 = 1.
- 1 + 1 = 10. If the sum of 2 bits is greater than 1, we need to shift a column on the left. In decimal system, 1 + 1 = 2. Binary notation of 2 is 10 (1 * 2^1 + 0 * 2^0). So we keep 0 in the 1's column and shift (carry over) 1 to the 2's column.
