The Math behind Dimensional Analysis 6 zooms x 4 zetas 3 zooms = 6 x 4 Zetas 3 = 24 Zetas 3 = 8 Zetas •This is the level of math you will need to know in this unit. •You would cancel out everything on the top and bottom that are the same (including words). • In the end, multiply everything on the top and divide it by everything that has been multiplied on the bottom.
