How does that commercial go? "Plug it in! Plug it in!!"

3a+b^2+4b-a
3*6+(-2)^2+4(-2)-6
16+4-8-6

If you need help with this type of problem, please take a look at my own explanation, and see if it is easier to understand than the one in your textbook. You can find my website by clicking on my tutor name "rapaljer" anywhere in algebra.com. From here, you can see and click on my website.

From my Homepage, click on the link "Basic, Intermediate, and College Algebra: One Step at a time." Choose "Basic Algebra", and look in "Chapter 1" for several topics: "Section 1.03 Signed Numbers", "Section 1.02 Order of Operations", and "Section 1.06 Variables and Subsitution." In addition to my own personal explanation of these topics, many of the exercises in this curriculum are solved in the "MATH IN LIVING COLOR" sections that go with it.

Math usually is NOT as hard as it looks! If it is taught properly, and if you get enough practice, you might surprise yourself at how well you do with it! Why don't you try my curriculum! I wrote it especially for students who have trouble with math! And it's all FREE!!
