### Exploring Wild & Wonderful Number Patterns

EWWNP means Exploring Wild and Wonderful Number Patterns Created by Yourself! Investigate what happens if we create number patterns using some simple rules.

### Steps to the Podium

It starts quite simple but great opportunities for number discoveries and patterns!

# Investigating Pascal's Triangle

##### Stage: 2 and 3 Challenge Level:

You can probably see all kinds of things to explore. Those of you who are familiar with spreadsheets can extend the pattern further. You would put 1, 2, 3, 4, 5, 6, 7, 8, 9, 1, 2, etc across the top and then you have to add the first 1 with nothing/zero that's beneath it to get the next line started. Let me show you clearly, here's the first part of the spreadsheet I used:

So, row 2 is simply the numerals going 1, 2, 3, 4, 5, 6, 7, 8, 9, 1, 2, 3, 4, etc.
Row 3; C3 is made from B3 + B2; D3 = C2 + C3 etc.[C3 = 1 + 0, D3 = 2 + 1 etc.]
Row 4, is made up in the same way so, D4= C3 + C4, etc.

So those formulae can be put in easily and then dragged through the other cells.
BUT we are dealing with digital roots which the computer deals with as MOD 9 [a kind of clock going from 1 to 9].

Let's have a look at the formulae that we need for the 4 cells in row 3, they are as follows,

Once you have these you can drag the formulae through more cells to the right and also down.

In this way you can extend the pattern as long as the spreadsheet will allow.

Enjoy!
