I am confident that if you have made it this far into unit 1, you have for sure understood the difference between arithmetic and geometric series. An infinite geometric series can be used for word problems and solved using formulas. Here are some videos that will definitely help you with your homework questions from your…

1.4 Geometric Series
After learning more about geometric sequences, it’s time to learn more about geometric series! Here are some videos that will definitely help you with your homework questions from your workbook! How to Find the Sum of Each Geometric Series Writing The Geometric Series Using Sigma Notation Word Problems If you have any questions, feel free…
1.3 Geometric Sequences
Now that you are familiar with arithmetic sequences and series, it’s time to learn about geometric sequences! A geometric sequence has a common ratio of r, unlike an arithmetic series, it has a common ratio rather than a common difference. Here are some videos that will definitely help you with your homework questions from your…
1.2 Arithmetic Series
Now you have a better understanding of arithmetic sequences, it’s time to learn about arithmetic series! Here are some videos that will definitely help you with your homework questions from your workbook! How to Find the Sum of an Arithmetic Series How to Find the Indicate Value Given Using the Information Given How to Find…
1.1 Arithmetic Sequences
Welcome to the first unit of Pre-Cal 12! You may be wondering, what is a arithmetic sequence? The whole concept of sequences and series may be new to many of you, but don’t worry, this Math Department Blog is here to help you learn more about these concepts! Here are some videos that will definitely…
1.6: Exponent Laws
If the exponent have the same base all raised to the same power, it will equal ‘1’ Anything to the power of 0 will always equal ‘1’ when there is an exponent multiplying another exponent with the same base, add the exponents to simplify it when there is an exponent dividing another exponent with the…
1.5: Orders of Operations
B Brackets E Exponents D Division M Multiplication A Addition S Subtraction Brackets are the top priority for order of operations. If there are bigger brackets around another set of brackets, work from inside out Exponents are below brackets. If there are no brackets, do exponents first, and if there are brackets, do the brackets…
1.4: Defining a Power
Exponential Notation: ex. 2x2x2x2x2 = 25 ex. 2x2x2x2x2x2= 26 ex. 2x2x2x2x2x2x2= 27 Notes: Even number of negative signs= positive number Odd number of negative signs= negative number –26 is ONLY putting the ‘2’ to the power of 5, NOT the negative. Therefore, the answer would still be negative because (-)(2)(2)(2)(2)(2)(2) = -64 (-2)6 is putting…
1.3: Square Roots of Non-Perfect Squares
Non Perfect Squares: numbers that can’t be multiplied into by two of the same rational numbers Ex. √48, √33, √6 These numbers are non-perfect squares because no numbers can multiply into it by itself (2×2 won’t work, 3×3 won’t work, 4×4 won’t work, 5×5 work work etc.) non-perfect squares are considered to be irrational
1.1: The Real Number System
Natural Numbers: Positive Whole Numbers (no decimals or fractions) NOT INCLUDING ‘0’ ex. 1,2,3,4,5,6,7,8,9,10,11……….. Whole Numbers: Positive Whole Numbers (no decimals or fractions) INCLUDING ‘0’ ex. 0,1,2,3,4,5,6,7,8,9,10,11……….. Integers: All Whole Numbers (no decimals or fractions) that are positive or negative. ex. -5,-4,-3,-2,-1,0,1,2,3,4,5 Rational Numbers: Any numbers that can be turned into a fractions. ex. 2,…
