Pascal's Triangle Spreadsheet

This is a random thing I made.

It’s pretty straightforward to set up.

1. set up the formula, say for B2: “=A1+A3” and copy and paste it into all the cells underneath.

2. Choose a cell at the top in the middle somewhere. Type “1”. It should fill in with Pascal’s Triangle automatically.

3. Set the conditional formatting to make empty cells white and colour in multiples of the contents of one cell (I used cell I8)
   something like this: “=AND(MOD(A2,$I$8)=0,A2<>0)”
