How Does Binary Counting Work?

Start with a question

Binary uses only 0 and 1; its place values are 1, 2, 4, 8 and 16.

Let us build the idea one small step at a time.

See the idea

See how counting changes when a number system has only two symbols.

Imagine the parts as helpers working together. Each part has a clear job and follows clear rules.

Connect it to a computer

In a real computer, data moves between programs, memory and hardware as bits. The example helps us understand the model, while the circuits and instructions do the real work.

Try a small example

Make a prediction, change one input and check the result. Explaining what changed is a powerful way to learn.

What to remember

How Does Binary Counting Work? becomes easier when we connect a familiar example to the real computer model. Keep asking what goes in, what happens next and what comes out.
