You might be wondering why you would need a calculator at the grocery store. To the left is exhibit A. Go figure:

- Four Muffins
- 180 Calories per serving
- 11 servings

Here's where the calculator is needed:
- 11/4 = 2.75 servings per muffin
- 2.75 x 180 = 495 calories per muffin


I believe it's safe to assume that you would eat an entire muffin. So, instead of consuming 180 calories, you will actually be chowing down on 495.

As an aside, the front label states: 0 trans fats. On the back label, it states: partially hydrogenated. That's a fancy way of saying trans fats. So, in each muffin there are, in fact,  trans fats. It also states on the back label: not a significant source of trans fats. 

Considering that trans fat is a known killer, I always assume any amount of trans fat is significant. I also don't like being lied to!
