Math Magic – Matrices Page 1 Working With Matrices: A. Number Sense only deals with small matrices‚ usually 2 x 2 matrices. This page will look at 3 ways of manipulating matrices: Multiplying Matrices‚ Inverses‚ and Determinants. B. Multiplying Matrices 1. Unlike general multiplication‚ matrix multiplication is not commutative. Multiplying A x B and B x A will give different results. 2. The following will show how to multiply two 2x2 matrices: a. In other words‚ you multiply the row of

Unit 4 1.Five advantages of using global variables. It is accessible to all the modules in a program You only have to declare it once outside the modules It is good to use it for constants you want to keep consistent It simplifies maintenance‚ avoids duplication of local constants. It can make a program easier to read in reference to constants. Five disadvantages of using global variables. It makes debugging difficult Any statement in a program can change the value If modules use
