Base 5 - Quinary |

If you understand the decimal (base 10) number system we use in our everyday lives, then you already understand the quinary (base 5) number system. You just don’t know that you know yet.

We use the decimal (base 10) number system in our day-to-day living. Base 10 has ten numbers (0-9) and orders of magnitude are times 10. The lowest-order number represents itself times one. The next-order number represents itself times 10. The next order number represents itself times 10x10 or itself times 100. The next order number represents itself times 10x10x10 or itself times 1000. And so on.

A decimal base 10 example would be the number 2417. This number means there are:

- seven 1’s,
- one 10,
- four 100’s,
- and two 1000’s.

## The Quinary, Base 5 Numbering System Uses the Same Structure...

...the only difference being the order of magnitude. Base 5 has five numbers (0 1 2 3 4) and orders of magnitude are times five. The lowest-order number represents itself times one. The next-order number represents itself times 5. The next order number represents itself times 5x5 or itself times 25. The next order of magnitude would be 5x5x5 or 125. And so on.**A base 5 to decimal base 10 example**would be the number 3142. This number means there are...

- two 1’s,
- four 5’s,
- one 25,
- and three 125's.

**Another base 5 to decimal base 10 example**would be the number 2011. This number means there are...

- One 1,
- one 5,
- no 25's,
- and two 125's.
