About this ebook

I HATE MATH.....There I said it! I bet thousands of students and parents have said it. When I was really having problems with Algebra in the 9th grade, my Grandmother ( who was a teacher) told me "math isn't hard if you understand it".

When I started my career in teaching math in Jacksonville Florida I soon learned that all the math books we had were lacking really good easy to understand instructions on explaining specific areas. Most of the math books did have good parts i.e. one might have a really good section or chapter on fractions but lacked in explaining decimals etc. I taught 7 years plus both sessions of summer school for 5 years at several junior and senior high schools. Each school had "adopted" different math books to teach from. This is where the idea of creating my own math book self guide stated. Over several years I started writing and explaining the different areas of math. It is my hope that this workbook helps students and parents who my be frustrated with "new" math and "common core" principles. In this workbook you will find every area that is covered in math for secondary students. The chapter problems are specially designed to address several levels of a students skill sets. I found that most students would fall into various levels....advanced; standard; basic and remedial. Each chapter problems and chapter tests are designed with levels of "difficult", "moderate" and " easy" problems. As a former math teacher and a parent of three adult children I really hope this book helps.

    About the Author

    Chapter 1

    Roman Numerals

    Today we see Roman Numerals on clocks, books, watches, movies, and even on our dollar bill. The Romans used a system of counting different from the system we use today. Below is a table of the values of their system. Notice that all 7 of the numbers begin with either 1 or 5. The Romans did not need 0, 2, 3, 4, 6 etc. By placing 2 X's together, they added their value and got 20.

    The last 4 letters L C D M can be remembered by the sentence; "Little Cows Drink Milk".

    If several letters are together, figure their value by starting at the left and work toward the right. If a letter of smaller value is to the RIGHT of a letter of a larger value, add the values together; XVI = 10 + 5 + 1 = 16. CLX = 100 + 50 + 10 = 160. If a letter of smaller value is to the LEFT of a letter of larger value, subtract the smaller value from the larger value; IX = 10(X)—1(I) = 9. XL = 50(L)—10(X) = 40. CD = 500(D)—100(C). It is never necessary to have more than three of the same letter values together.

    Always go to the next higher value; XXXX = 40, instead use XL (50 - 10 = 40), CCCC = 400, instead use CD (500 - 100 = 400).

    Note: VL IS NOT USED FOR 45, BECAUSE A SMALLER LETTER IN FRONT OF A LARGER LETTER MUST BE A NUMBER THAT BEGINS WITH 1.

    Only 1, 10, 100 can be used in front of larger numbers.

    Roman Numerals (Continued)

    XCV = (100 - 10) + 5 = 95 (not the letters VC)

    MCMLXXV = 1000 = (1000 - 100) + 70 + 5 = 1975

    LXXI = 50 + 20 + 1 = 71

    XV = 10 + 5 = 15

    XIX = 10 + (10 - 1) = 19

    XLIX = (50 - 10) + (10 - 1) = 49

    To change a decimal number to a Roman numeral begin with the first number on the left and work to the right.

    173 = CLXXIII

    100 = C

    70 = LXX

    3 = III

    173

    For large numbers the Romans used a line drawn across the top of the numeral to mean that the value is multiplied 1000 times.
