Permutations and Combinations
If there are 5 dishes, they can be relished in any order at a time. In permutation, it should be in a particular order. In combination, the order does not matter. Take 3 letters a, b, and c. The possible ways of pairing any two letters are ab, bc, ac, ba…

Chapter 4.8, Problem 2C

In Questions 1—4, simplify each expression. Aside from what we covered in the Group portion of this lesson, here are some things you should keep in mind:

Order of operations: Multiplication always comes before addition or subtraction.

The distributive property is needed when multiplying a number or variable by a sum or difference.

When subtracting, don’t forget to subtract EVERY term in an expression. That’s what the parentheses are there for!

( 5 x 2 + 3 x + 2 ) − ( x 2 − 2 x + 7 )
