I was trying to find the sum of the widths of both of my monitors so I coulc make a canvas that width in Photoshop.

I first used OS X's calculator, and to my surprise and anger, the canvas was much to large for both of the screen shots of my monitors. I was like, "What the heck? Why is the canvas so big?!"

I decided to add the widths myself and got 2960 instead of the 3000 that OS X's calculator was giving me. I double checked my answer remembering that Google had a calculator and it too told me the sum was 2960.

I made a new canvas with a width of 2960 in Photoshop and it was the perfect size. I'm just amazed that OS X's calculator won't do this simple math.

Try it out if you have a Mac and email me if you had the same thing happen in OS X's calculator as I did, or if it is adding correctly.
