Welcome to the use of ALGEBRA I - VERBAL PROBLEMS . There are three files on the disk. You must have all three in this SHAREWARE version.
README - This is the file you are reading now. It only tells you what
each file in the set does and is not needed to run the
programs. But it handy to know what to do.
ALG13A.PRG - This is the BOOT program for this disk. In the SHAREWARE
version you must load this PRG file first, read the
documentation if you want, print it out or print out
an order form. Or you can just use the arrows to go
to the MENU and select ALGEBRA I - V. PROBLEMS
and press ENTER and the main program will run.
ALG13B.PRG - This is the main program and if you have read or printed
out the documentation then you know the power it has to let
you configure it for your own uses.
When you register your version (directions are in the BOOT program) you will receive an updated version, printed documentation, and the program will include all working functions. THANK YOU AND ENJOY!!!

The ALGEBRA I SERIES developed by Educational Management
Systems under the guide of Charles O. Gauthier, Senior Programmer,
is based on twenty years of teaching Algebra I by Mr. Gauthier
from three different text series.
The program on this disk has many features:
* The user may store or retrieve the results of any work
session to or from disk
* The user may print worksheets with as many problems as
wanted, and each would be different - there is also the
option to select the help sections to be printed also to
make them instuctruction worksheets
* There are three levels of help available with each separate
problem, and the help is geared toward helping the user to
understand the specific skill for that particular problem
* The entire operation of the program is within the user's
control - allowing the work session to be as long short as
the need be
* The work and program changes use the GEM interface as much
as possible - for ease of use
* The user may go to the SELECT menu and make the problems
more difficult, work more problems, select a higher range
of digits etc.
* From the OPTIONS section of the FILE, the user may change
their name, the date, save a file, input a file, see the
scores on screen or to the printer, or any of the other
OPTION functions
* Randomly generated number make each problem in each program
different - and worksheets with many of the same type of
problem will ALL be totally unique problems
VERBAL PROBLEMS:
There are 30 different types of verbal problems in 10
different areas of work that are found in all current ALGEBRA I
texts used within curriculum.
Each HELP section starts with a definition of what X should
be, and leads the user into the relationships of that particular
type of problem ( i,e.: age uses a chart, motion uses the distance
formula with a chart, geometry uses the correct formula, etc.) and
in the final step sets the equation up.
It is assumed that the user knows the axioms and properties in
LINEAR EQUATIONS before working VERBAL PROBLEMS.
The types of problems covered are:
NUMBER - These cover sums, differences, separate into three parts,
consecutive integers and others.
AGE - These cover the basic ideas of age relationships - one
person being older than another and then in so many years,
etc.
GEOMETRY - These cover area, perimeter, right triangles,
complementary angles and the Pythagorean Theorem.
MOTION - These cover uniform motion in still water and people
who meet when one of them leaves before the other.
MIXTURE - These cover mixtures selling at different prices and
percent solutions of water and alcohol.
COIN - These cover 3 types of coin and value relationship.
INVESTMENT - These cover interest earned on two investments and
a total invested at two different rates.
PERCENT - These cover the interest formula, selling price with
profit and overhead figured in, and also percent of
increase or decrease.
WORK - These cover work by two people, work where one person
starts before another and also covers the capacity of
LEVER - These cover weights and distances where one distance in
not known and another where the total length is known.
Algebra I - Verbal Problems
This version of Algebra I - Verbal Problems was written for the
beginning student in algebra. There are some assumptions about the
level of algebra that one needs to know before working this
program.
1.) The student would have a working ability to translate from a
verbal statement into the algebraic representation using LET X
statements and then be able to set up and solve an equation.
EXAMPLE:If a number is increased by twice itself the result is 12.
LET X = a number
LET 2X = twice a number
X + 2X = 12
________ _______
a number increased by twice result is 12
2.) The student would have a working knowledge of equation solving
techniques and know the axioms of equation manipulation.
EXAMPLE: Solve 5( X - 4) -3(3x + 6) + 42 = 8
clear parentheses 5X - 20 - 9X - 18 + 42 = 8
use the commutative
property to combine 5X - 9X - 38 + 42 = 8
like terms
-4X + 4 = 8
Use the additive
inverse to combine -4 -4
like terms across the ---------------
equal sign -4X = 4
divide by the --- ---
coefficient of -4 -4
the variable
X = -1
These titles will be available in a HOME VERSION and a SCHOOL SITE
VERSION. The difference being that the SCHOOL SITE VERSION will be
sold to a school and the school will have a license through the
purchase to make duplicate copies for use within that single
school, or use within a network off a hard disk drive.
But more importantly there is a separate program for the teacher
to enter classes, class lists and do managed instruction from any
of the series titles for individual students the results of which
will automatically be saved to disk. The teacher can then assess
this information and make changes as appropriate.
It is very important to understand that written into the programs
are controls that allow the user to make changes in the parts that
effect the numbers, their size, use of negative numbers etc. in
order to make the program as customized as it can be for each
user.
Also OPTIONS are included that make it possible for the user to
make use of the data generated from their use of this program,
including generating worksheets of randomly generated problems,
dumping to the printer problems that the user is not able to
master for future study, saving to disk at any point a file with
the results of the work up to that point, bringing in from disk
any past file and many other OPTIONS.
It is hoped that the purpose of this program:
to help students understand word problems
in ALGEBRA I
will benefit those who spend the time working with it.
Thank you for using ALGEBRA I - VERBAL PROBLEMS
