Working out the pip decimal position?

I’ve been getting trained to make my future on the forex, but due to being a little slow at maths I have always struggled with converting all the different pip values/points etc.

Does anyone know an easy way to understand what the pip decimal position is for currencies/commodities?

In particular, I am required to add the spread between the sell/buy which is displayed in PIPS to the ATR, which is displayed in points - I hope I’ve made myself clear enough but if anybody needs clarification let me know.

Many thanks in advance!
