## First 25 Questions of OpenStax Pre-algebra Review:

These first 25 questions involve solving basic algebraic equations; translating word problems into algebraic expressions; solving word problems; using order of operations to solve integer expressions; and simplifying fractions and rational expressions.

By watching these, you’ll easily learn the basics of the simpler algebraic equations, expressions, and word problems you’d encounter in a pre-algebra or algebra class.

In the pics below, you’ll see the actual questions (1-25) you’ll encounter in the video:

## OpenStax Pre-algebra Video Tutorials, Questions 26-37

This next set of questions covers complex fractions, solving fractional equations, and simplifying decimals. Also, there’s a question asking you to order fractions and decimals from smallest to largest. It helps if you are able to convert from fraction to decimal form. If not, you can watch the video and learn it there. It shouldn’t take but a minute or two for you to learn.

Please keep in mind that you’ll see one or two ways to solve or simplify an algebra or pre-algebra problem. While there are more methods and approaches that are valid, here you’ll watch the simpler, more intuitive methods. You will see more sophisticated approaches later in more complicated algebra problems.

In the pic below, you’ll see the actual questions (26-37) you’ll encounter in the video:

## OpenStax Pre-algebra Video Tutorials, Questions 38-43

Questions 38-43 deal with random topics, such as circumference and area of a circle, given radius; mean, median and mode of sets of numbers; and per unit price of an item given the price of 3 of the items.

In the pic below, you’ll see the actual questions (38-43) you’ll encounter in the video:

It’ll help you to know the formulas for area and circumference of a circle. Same, too, for the definitions of mean, median, and mode. Mean is the average; median is the middle number, or average of two middle numbers; and mode is the most frequently occurring element within a set. You will see all of this explained in the video.

## OpenStax Pre-algebra Video Tutorials, Questions 44-49

Questions 44-49 deal with decimals: decimal word problems, commission word problems, discount rate, and simple interest. All of these are worked out by hand. While you can use a calculator, you can still survive these without one.

In the pic below, you’ll see the actual questions (44-49) you’ll encounter in the video:

## OpenStax Pre-algebra Video Tutorials, Questions 50-57

Questions 50-57 are a random assortment of prealgebra and algebra topics. Some are fractions, others are unitary conversion. And, there’s a typical number set question thrown in as well. The word problems are easier than what you might be expecting.

In the pic below, you’ll see the actual questions (50-57) you’ll encounter in the video:

## OpenStax Pre-algebra Video Tutorials, Questions 58-67

Questions 58-67 focus on variations of linear equations. By learning these from the video, you’ll be able to handle almost all of the types of linear equations you’ll encounter in a pre-algebra class. Even if you’re in an algebra class, you’ll benefit from the variety of linear equations you’ll see worked out in the video.

These linear equations cover the typical types of linear equations you’d expect to encounter in a pre-algebra or algebra class.

In the pic below, you’ll see the actual questions (58-67) you’ll encounter in the video:

## OpenStax Pre-algebra Video Tutorials, Questions 68-73

This problem set covers a variety of word problems: number questions; coin problems; and angles. If you want to understand how to approach such questions, you will want to watch the video.

## OpenStax Pre-algebra Video Tutorials, Questions 74-76

This short set of questions deals with geometric word problems. In the video, you’ll see the equations needed to set them up along with the methods you’ll use to solve them.

In the pic below, you’ll see the actual questions (74-76) you’ll encounter in the video:

## OpenStax Pre-algebra Video Tutorials, Questions 77-82

These problems are all polynomials. One is subtracting two trinomials, while the others deal with multiplying monomials and raising monomials to powers. In the video, you’ll see a short review of laws of exponents to guide you through what you need to know to simplify these expressions.

In the pic below, you’ll see the actual questions (77-82) you’ll encounter in the video:

## OpenStax Pre-algebra Video Tutorials, Questions 83-89

Questions 83-89 concern multiplying two binomials, multiplying a binomial with a trinomial; dividing monomials; and multiplying monomials.

Below you will see a picture of the actual questions covered in the video:

## OpenStax Pre-algebra Video Tutorials, Questions 90-91

These two questions concern writing large and small numbers in scientific notation and finding the greatest common factor of a trinomial. Below you can see the actual questions from the problem set in the video:

## OpenStax Pre-algebra Video Tutorials, Questions 92-97

All of these questions concern graphing linear equations. While most are in y=mx+b form, a couple of them are not. You can see the actual questions below:

## OpenStax Pre-algebra Video Tutorials, Questions 98-101

More graphing linear equations. Some are in standard form; some give only a point and a slope; one asks you to find the slope of a given graphed line; one asks you to find slope given two points. The actual questions are below:
