Algebra 1: Part 1 





Hello, All My Students! I am hoping all of you can work as hard as I know you can! This course will go from easy to hard for you. See, at first it all is basically review, but as we go it will get harder at a nice steady rate. So, dont think this is going to be easy, because it isn't. This course will take actual work AND effort to pass! Anyway, I hope you all enjoy this course as much as I did when I was your age. Have Lots Of fun! Ms. Perry How It Works: On all the activities I want you to email me when your done with them all, and tell me how long it took you to do each one, and I want you to tell me your own opinion on how you did each. This will effect your grade! On the quizes I want you to email me afterward and tell my exactly how you did. NOTES TO TAKE AND STUDY BEFORE QUIZ!!!!!! Any letter that is representing a unspecified number is called a variable. An algebraic expression consists of one or more numbers and variables along with one or more mathmatic operation. Her are some examples: b + 4 s/t  1 a * 4n 8rs / 3k In a multiplication expression, the quantities being multiplied are called factors and the result is called the product. In algebraic expressions, a raised dot(in our case *) or parentheses ar often used to indicate multiplication. When variables are used to represent factors, the multiplication sign is usually omitted. Here are 5 ways to represent the product of a and b . ab a * b a(b) a x b (a)(b) Fraction bars are used to indicate division. To solve some verbal problems in mathmatics, you can create a algebraic expression or translating the words into mathmatical symbols. The chart below shows some of the words that are used to indicate mathmatical operations ADDITION: Ex. 1 Write an algebraic expression for: the sum of a and b a + b Ex.2 Write an algebaic expression for: a number k divided by a number n k / n Ex.3 Write a verbal expression for 4x the product of 4 and x, or 4 times x Ex.4 Write a verbl expression for z  6 6 less than z, etc. In an expression like 10 cube, 10 is the base and 3 is the exponent. The exponent indicates the number of times the base is used as a factor. 10 cube means 10*10*10 a square means a*a
