Permutations | Algebra | Chegg Tutors

A permutation of a number of objects is the number of different ways the objects can be arranged, keeping order in mind (that is, which is first, second, third, and so on). When choosing some objects from a larger number of objects, the position of the chosen objects is also important. Think about permutation problems as the order of r objects selected from n distinct objects, or n objects taken r at a time.

For example, six students enter a contest. In how many ways can the first three places be determined?
Note that n! is the number of permutations (ways of arranging) exactly n things.

TEACHING EXPERIENCE
I spent two years living in New Jersey and teaching individuals and families life principles they could utilize to improve their own situations as well as relationships with others. I have also tutored many students in math classes ranging from Algebra 2 to Advanced College Algebra, and I also have had some experience with tutoring in basic physics.

EXTRACURRICULAR INTERESTS
I grew up in California (around the Bay Area) until I was 10 and then my family moved to Highland, Utah where we have lived ever since (with the exception of the two years I spent in New Jersey). Some of my hobbies included baseball, assembling jigsaw puzzles, various forms of entertainment (mainly video games and movies) and getting together with friends. I believe students would enjoy knowing that I genuinely care to make certain I’m more interested in helping them than in filling a quota. If they would benefit from a different approach to help them better learn concepts I am more than willing to shake things up and try something new.
