# How To Solve A Algebra Problem

The main difficulty is translation of the details of the word problem into the kinds of mathematical expressions that you have learned to handle. This step may seem obvious, but you will save yourself much time and difficulty if you take some time to carefully read what the problem says. A word problem may provide you with enough details to calculate all sorts of parameters, but the problem probably will only be asking for one or two. You don't need to be an artist to do this-just draw something that you can understand and that helps you organize your thoughts about the problem. The mathematical expressions that you glean from the word problem will involve an unknown value (or values) at some point (one of which may be the result from step 2 above); try to identify what this value is and assign it a variable symbol. Problems from the real world involve units, and you need to keep track of them. If you have carefully performed the preceding steps, you should be in good shape to write the correct expressions. The result should be a solution that fulfills the requirement you wrote down in step 2 (that is, whatever the problem is asking for). Does the problem ask for a speed but you've ended up with units of acceleration in your answer?Here are some steps that will help you organize the process of translating from words to mathematical expressions that you can solve. You may not be able to visualize all the details, but you should gain a mental picture of what is generally being discussed. Thus, figure out what you are trying to find and write it down. If the problem involves a moving automobile, for instance, you don't need to draw a professional rendition when a box or something similar (even marked "car" if necessary) will do. Write down this assignment for reference as you solve the problem (for instance, " = the velocity of the car"). You've probably gone astray somewhere along the line.

Before you start solving word problems in algebra, you should first already know about real numbers, how to manipulate algebraic expressions, and how to solve math problems involving linear equations and inequalities.

We will focus on application of these concepts through word problems.

Modern algebra also arguably contains the field of number theory, which has important applications in computer science.

(It is commonly claimed that the NSA is the largest employer in the USA of mathematicians, due to the applications of number theory to cryptanalysis.) However, number theory concerns itself with a specific structure (the ring ), whereas algebra in general deals with general classes of structure.

If his trip was 450 miles, how long did it take him to reach his destination?

As a first word problem, this one may seem a bit intimidating; don't let it discourage you, though.

Let's look at a couple quick examples (note that although these examples use plural and singular units for ease of reading, whether a unit is written in its plural or singular form has no bearing on the meaning or the math): This second example is actually a case of identity, because 12 inches = 1 foot. We can thus see how the presence of units has an effect on the math, but the same general principles that we have studied still hold. Let's multiply by factors with corresponding units that convert from years to seconds as follows.

(Again, note that we are actually multiplying in each case by 1 because of the relationship of the units.) Thus, 1 year = 525,600 minutes, or (alternatively) there are 525,600 minutes in a year.

Algebra Involving Equation Algebra can be used to solve equations as simple as 3x=9 but in some cases so complex that mathematicians have not figured how to solve the particular equation yet.

As if to add to the confusion, "algebra" is the name for a certain kind of structure in modern algebra.
