So we don't have to really worry about that. However, you must be able to rewrite equations in both forms. Concepts About the Author Lisa studied mathematics at the University of Alaska, Anchorage, and spent several years tutoring students at the college and high school levels.

Perhaps you just mean to convert it from "summation form" ("sigma form") to a written out form? For something like #\sum_{i=1}^{n}i^{2}#, the summation symbol #\Sigma# just means to "add up". Putting an #i=1# underneath the summation symbol means to start the value of #i# at 1.

It is then assumed that #i# keeps increasing by 1 until it reaches #i=n#, where #n# is the number above the summation. Mathman teaches place value expanded form the fun way with this maze style math game.
