The Math Matrix

I LIKE ABSTRACT STUFF; WHY SHOULD I CARE?

Systems of equations can also be represented using matrices. A matrix is a rectangular grid full of numbers, such as

The great thing about a matrix is that it keeps all those floating numbers trapped inside a box, so they can’t escape. It might need to plug up a couple of holes at the top and bottom, but it’s better than nothing.

The word “matrix” has many interesting meanings. There’s a movie called The Matrix. (We’re not counting the “sequels,” and you can’t make us.) There’s also a matrix in the science fiction television series Dr. Who. There was a character named “Dot Matrix” in the movie Spaceballs. We could go on, but we’re getting tired of all the linking.

Anyway, back to math. The system of equations

could also be written as a matrix equation:

The subject of linear algebra deals with ways to solve matrix equations, as well as various other things relating to matrices. For example, if you get married one day, you may want to have a Matrix of Honor by your side.

Case Competition: Adventure Trip Logistics

  1. Locate a place in Alberta for an Adventure-trip proposal.
  2. Brainstorm a list of expenses.
  3. Estimate the cost of the trip expenses for everybody
  4. Find out the ration of how much it would cost per person
  5. See if this is on-par with the current $350 pp estimate.
  6. Compare 2 different motels or campgrounds to stay
  7. Find the price for the group
  8. Find the ratio of price per person per night for accomodations
  9. What is the ratio of rooms needed for the group for both boys and girls?
  10. What percent of time should be spent on a) fun b) learning c) rest (zzzz) d) cooking/eating
  11. How long will it take to travel there, with rest breaks? (what is the rate of travel in average km/hr?)
  12. What is the rate of fuel consumption?
