this is a math numerical expression that uses addition, subtraction, multiplication, division and exponents. If you can not use those i suggest you not do this. To change slides go in number order to reach the right page (1,2,3,4,5,6,7,8,9 ect.) Some pages have animations so stay on a slide long enough to see them. Scroll down to see answer. answer also shown on last slide. enjoy! 4
