Introduction~
------------
Algebra Drills is a series of randomly
generated exercises designed to
challenge a student's knowledge in
22 areas of algebra.
The program is intended for algebra
students on the secondary and
postsecondary levels. Exercises range
from basic number properties to
advanced trigonometric functions.
Making a Backup Diskette~
------------------------
It is important to make a backup copy
of your Algebra Drills diskette in
case your original diskette is lost or
damaged. If necessary, refer to your
Disk Operating System (DOS) book for
information about using the DISKCOPY
command.
Store the original diskette in a safe
place and use the backup copy to run
the program.
2
Installing on a Fixed Disk~
--------------------------
Follow the steps below to install the
Algebra Drills program on your fixed
disk:
1. Create an Algebra Drills
subdirectory on your fixed disk.
You might want to name it ALGEBRA
or something similar.
2. Insert your Algebra Drills
diskette in drive A and enter: A:
3. At the DOS prompt A>, enter:
copy: a:*.* c:\algebra
where ALGEBRA represents your
Algebra Drills subdirectory.
Getting Started~
---------------
Follow these steps to start Algebra
Drills:
1. At the DOS prompt, type:
algebra
2. Press Enter to start the program.
The Algebra Drills title screen
appears.
3. Press Enter to continue.
The Algebra Drills Main Menu
screen appears.

The Main Menu~
-------------
This section describes each of the six
algebra topics on the Main Menu.

Introductory Algebra~
This topic introduces you to the
fundamental properties of algebraic
expressions. Questions cover number
properties, inverses, absolute values,
integers, square roots, and
inequalities.
Polynomial Equations~
This topic includes comparing and
solving monomial and polynomial
equations. It also includes identify-
ing positive roots, solving solution
sets, and finding the smallest or
largest values of polynomials.
4
Operations with Fractions~
Select this topic for drills involving
fractions, ratios, and proportions.
Drills cover adding, subtracting,
multiplying, and dividing fractions and
solving, simplifying, and comparing
ratios and proportions.
Linear Functions~
This topic reviews the different
components of linear functions, and
asks you to identify the slope, x and y
values, or the y-intercept of
y=mx+b equations. Drills also cover
factoring lateral functions and solving
systems of equations.
Geometry~
Drills for this topic review geometric
properties of circles, triangles,
complementary angles, and the
Pythagorean Theorem.
Trigonometry~
Select this topic for drills involving
the sine, cosine, and tangent of
trigonometric equations. Right
triangle equations are also covered.
Note: A Trigonometric Table
is located at the end of this
document to assist you in doing
trigonometric calculations.
5
Selecting a Drill~
-----------------
Follow these steps to select a drill:
1. Select a topic from the Main Menu
by pressing the number next to the
topic you want to practice.
A second menu appears, called the
Drills Menu. This menu displays
the list of drills for the topic
you selected.
2. Select one of the drills on the
Drills Menu by pressing the number
next to the drill.
3. Press Enter to start the drill.
Answering Questions~
-------------------
Questions are in two formats:
multiple choice and short answer.
Multiple choice questions provide four
answers from which you can choose.
The screen displays:
Enter your answer (1-4): [ ]
Type the number of the answer you think
is correct.
Then, press Enter to continue.
Short answer questions do not provide
a list of answers. You must enter the
answer to each question. You might
want to work out each question on
paper. When you have an answer, type
it after the prompt:
Enter your answer: [ ]
Then, press Enter to continue.
6
If you answer a question
correctly, the program tells you that
your answer is correct.
If your answer is incorrect, the
program displays the correct answer.
To go to the next question, press
Enter.
You can answer as many questions as
you like during a drill.
Scoring~
-------
You receive one point for each correct
answer. Points are not deducted for
incorrect answers.
To view your score for the current
drill, press F4. Press Enter to
continue the drill.
Use your score to help identify areas
where you need additional practice or
instruction.
Ending a Drill~
--------------
To end a drill:
1. Press Esc.
The score for the drill appears.
2. Press Enter to return to the
Drills Menu.
You can either select a new drill from
the Drills Menu or press Esc to return
to the Main Menu.
To end the program, press F10 when the
score is displayed at the end of a
drill or press F10 when you are at the
Main Menu.
7
Options~
-------
Algebra Drills provides four options
that allow you to change some of the
features of the program. To see the
Options Menu, press F2 when you are
at the Main Menu. The Options Menu
appears.
