**What is Binary?**

Binary, or base two, is another way to represent numbers.

The main difference between binary and decimal (“normal numbers”) is the number of symbols we can use.

In decimal, we have 0 through 9, ten total symbols.

However, in binary, we only have two symbols 0 and 1.

To avoid confusion, the rest of the numbers will be written using a notation.

If X is a number in binary and Y is the same number in decimal, it can be written as:

X[BIN] = Y[DEC]

The way binary works is as follows:

1[BIN] = 1[DEC]

10[BIN] = 2[DEC]

100[BIN] = 4[DEC]

Each digit is 2 times the value of the digit to its right (previous digit).

If we want 3 in binary, then we simply merge 1 and 2:

11[BIN] = 3[DEC]

101[BIN] = 5[DEC]

110[BIN] = 6[DEC]

111[BIN] = 7[DEC]

In redstone, binary is usually represented with on being 1 and off being 0.

With this representation, we can make redstone circuits capable of doing arithmetic and logic operations on binary values.

This isn’t meant to cover ALL binary topics, just a simple explanation of binary.
