### WolframAlpha Gives Math Solutions Quickly

Type your math problem into the box above and get a solution quickly. If the problem is to  graph a linear equation, simply type "plot y=2x+7" or "graph y=(-1/3)x-4".You can also graph 2 or more linear equations by adding an "and" between the linear equations. Ex. "plot y=2x+7 and y=2x-3". This example will show two lines that are parallel because their slopes are the same. Try entering 2 points to graph a line, get the equation of that line and the slope. Other things you might try are factoring polynomials, expanding binomials and simplifying expressions. By clicking on the title you will be directed to WolframAlpha website where you can find many examples of math, science and other subjects.

# How to Get an "A" in Geometry

from wikiHow - The How to Manual That You Can Edit

Geometry is a very challenging subject for many students. Many of the concepts are totally new, and this can make for a very scary experience. Through combining good study habits and a few study pointers, you can succeed in Geometry.

## Steps

2. Do your homework. Homework isn't just assigned to torture you, it also helps you learn, just do it.
3. Study with classmates. Two heads are better than one, three are even better. If you don't understand something, they might.
4. Use study tools. Does your book have an integrated website? Visit it. Having trouble remembering formulas? Make flashcards.
5. Make mnemonic devices. "Some Old Hippy Caught Another Hippy Tripping On Acid" reminds you of the formulas for sine, cosine, and tangent: Sine = Opposite/Hypoytenuse, and so forth--just use the first letters of every word.
6. Remember important terms. "Complementary" angles are those angles which add together to make 90 degrees, supplementary angles add to 180. Remember that "vertical" angles are always equal, as are "alternate interior" and "alternate exterior" angles. "Right" angles are 90 degrees, while "straight" angles are 180.
7. Prove everything. In most geometry courses, it's not enough to just remember that something is true, you must be able to prove it from simpler principles. You might be asked to prove that alternate interior angles are equal. Always ask yourself "how do I know this is true?" and then demonstrate the truth step-by-step. This way, even if you forget something important, you can still answer the question correctly because you can get to the answer on your own. This is how professional mathematicians do it.
8. Draw diagrams. Geometry is all about graphics, make use of them. If you're asked about some angles, draw them. Relationships like vertical angles are much easier to see in a diagram, if one isn't provided, draw it yourself.
9. Practice problem-solving. Geometry is as much a skill as a branch of knowledge. Simply studying the rules of geometry will not be enough to get an A, you need to practice solving problems. This means doing your homework and working extra problems for any trouble areas.

## Tips

• Get phone numbers and emails of 3 people in your geometry class.
• Meditate. This helps.
• Read the lesson you are going to cover in class the day before and know the formulas and postulates by heart.

• Do not cram.

## Things You'll Need

• A straight-edge
• A drawing compass
• A calculator

# How to Learn Algebra

from wikiHow - The How to Manual That You Can Edit

Algebra is central to all Mathematics. However, many people find it incredibly difficult to master algebra while others don't even need to try. For those who find algebra difficult, you have come to the right place, hopefully, this will help with your questions.

## Steps

1. Begin by knowing how to do multiplication, division, addition and subtraction and handle exponents, ratios and fractions.
2. When doing exercises in Algebra, ask yourself, What am I suppose to be learning from this?
3. Do the work until you fully understand the concept behind the exercises you are doing.
4. Do not skip over sections in your book, unless instructed to by your teacher. (Of course, you can skip over the review section in the front of the book).
5. You should not expect answers to always be clean in algebra.
6. Progress in algebra (and any other kind of math) requires work! Failure to work is why most algebra students fail.
7. Ask your teacher to help you receive a better understanding of algebra. If your parents don't know, then your teacher is the next person you should turn to. After a maths lesson, ask your teacher for help, either explaining the topic and giving extra work to max out the algebra methods.

## Tips

• You can search the internet (or Wikihow) for other tips and ways to do Algebra. There's more than one way!
• Be patient. Learning things can take time so don't quit
• If you discover a serious mistake in your work, DON'T ERASE IT! Put a line through it and write farther down the page. Expect to have to use a lot of paper.
• Remember what Einstein said," Do not be concerned with your difficulties in math. I can assure you that mine are still greater."
