Algebra I For Dummies®

Divisibility by 6: A number is divisible by 6 if it is divisible by both 2 and 3. Divisibility by 3: A number is divisible by 3 if the sum of the digits in the number is divisible by 3.

This easy-to-understand reference not only explains algebra in terms you can understand, but it also gives you the necessary tools to solve complex problems. Algebra rules To make everything work out right, you have to follow the basic rules of algebra (or mathematics in general). b>

Factor fearlessly, conquer the quadratic formula, and solve linear equations

There's no doubt that algebra can be easy to some while extremely challenging to others.

Still, it reminds me a lot of the stuff I took in math class 30 years ago and have since completely forgotten. p>Algebra I: 1001 Practice Problems For Dummies (9781119883470) was previously published as 1,001 Algebra I Practice Problems For Dummies (9781118446713).

Mary Jane Sterling has been teaching algebra, business calculus, geometry, and finite mathematics at Bradley University in Peoria, Illinois, for more than 30 years. The only way to figure out how the different algebraic rules work and interact with one another is to get into the problems and get your hands dirty, so to speak.r\n\r\nThe only way to figure out how the different algebraic rules work and interact with one another is to get into the problems and get your hands dirty, so to speak. p>

Now with 25% new and revised content, this easy-to-understand reference not only explains algebra in terms you can understand, but it also gives you the necessary tools to solve complex problems with confidence. Ok, I see a LOT of people complaining that this was TOO advanced and that it assumed you knew a little bit of algebra.

The book is a good one, with the exception of feeling like at times there's a bit of an assumption that presupposes mathematical knowledge on the reader's part. The language is clear, and the explanations seem to give just enough detail without being long-winded. O) When I hear or read a book title that includes the phrase, "for Dummies", I easily pull together the concepts that this book is not likely a foundational text for building one's doctorate upon, and that there might very well be some non-standard methodology in its construct. p>","authors":[{"authorId":8985,"name":"Mary Jane Sterling","slug":"mary-jane-sterling","description":"

Factoring quadratic trinomials

You can factor trinomials with the form ax² + bx + c in one of two ways:

\n
• \n

  Factor out a greatest common factor. Whether you want to brush up on your math skills or help your children with their homework, this book gives you power -- to the nth degree. Together these two books give students helpful supplemental instruction and plenty of practice to help them score high in their high school Algebra class . The emphasis is firmly on teaching the vocabulary and concepts used in algebra, so you will have them in your head when you start encountering actual problems and homework assignments. Finally, you get to the answer of that all-too-common question, When will I ever use this in real life?

  Unlike other subjects where you can just read or listen and absorb the information sufficiently, math takes practice.She is a graduate of the University of New Hampshire with a master’s degree in mathematics education.
