Resource type: Video

Reasons for recommendation: This is a very hilarious video of a man proving how 13 times 7 equals to 28. I found this interesting because it is basic math and if one does not learn his foundations well, he/she may end up like the guy in the video. That is why I feel that it is important to learn math now so in the future we can understand harder concepts.
