VIDEO CLIP: MATH trick

Comment from a viewer: I thought this video showed an interesting way to do multiplication. There are many ways to do a multiplication problem besides the old stand by and this is a good example of what one can discover if they put their minds to it. I wouldn t teach this strategy on a regular basis to my students, but it could be fun to see what my students could do with it. I imaging the problem would be quite time consuming with something more like 967 x 873. This may keep those overachievers busy for a while in class.
