Okay so I have to find how many total squares are in an 8 by 8 checkerboard. I have a roman letter thing that kinda looks like a capitol 'e' but without the middel line. On the bottom I have N=1 on the side of it i have N^2 and 8 on the top. Can anyone tell me how I use this to find how many total squares are in the 8 by 8 checkerboard.

Question

Thanks a bunch
