What are binary number systems?

Binary number systems are like having only two favorite toys to count with, 0 and 1.

Imagine you have a box of blocks, but instead of having 10 different colors (like in base 10), you only have two: red for 0 and blue for 1. That’s the idea behind binary numbers!

In regular counting, we use digits from 0 to 9, that’s why it's called base 10. But in binary, we only use two digits: 0 and 1, which is why it's called base 2.

Let’s say you want to count up to 3:

• 0 becomes 0
• 1 becomes 1
• 2 becomes 10 (like one blue block and one red block)
• 3 becomes 11 (two blue blocks)

It's like counting with your fingers, if you only had two fingers, you'd count in binary!

Computers use binary because they can understand only on (1) or off (0), just like a light switch. Every time you play a game or watch a video on a tablet, it's using binary numbers behind the scenes, making everything work smoothly!
