I use this more than my TI-83 I have a really difficult time with math. I've spent hours searching for an app that can do 3 basic things I need: 1)check my work 2)show step solutions 3)do so in a simple, user friendly way. One small gripe: the buttons are too small.

Christopher Brossmer

Wtf math Does a terrible job giving equations and answer process. If you are bad at math get ready to learn a new language. I refunded almost immediately. I should have put zero stars. No user interaction, just pre made equations with no clear steps to answer

## Pre-Algebra

Need more than free videos to learn math? YourTeacher's Pre-Algebra app is like having a personal math tutor in your pocket.

“It’s like a private school math classroom, but you are the only student.”

John

"I just love YourTeacher and the way you explain things. I felt like I was in a classroom instead of just looking at examples."

Diane

“Prior to using your Pre-Algebra program, my daughter had 6 test grades of 45-56. Once she was on the program, she had 4 test grades of 85-100. My 13 year old student actually sits down with the program on her own and completes the work with out me nagging her to do it. She does not have to be driven to another location, she is not losing school time to attend tutoring, nor am I losing time from work. I know the work she does is correct. I'm not praying that the tutor knows what he/she is doing. AND YOU CAN NOT BEAT THE EXCELLENT PRICE. This program works and is such a blessing. Thank you very, very much for this program."

## Pre-Algebra

MATH Domain is an educational app covering math subjects typically introduced in Pre Algebra. (More topics are steadily being added.)

MATH Domain is made-up of 4 main areas:

Learning Area

• explains math topics in an easy-to-read format

Concept Check Area

• quizzes the user on important concepts

Practice Area

• provides a practice area for several topics

• provides step-by-step solutions for practice problems

• supports Google Play's Leaderboards

• is where you can compete against friends or the rest of the World

• allows the easy sharing of progress results

Progress Area

• keeps track of progress made in the practice areas

• displays progress made on Leaderboards and Achievements

Who is this App for?

Currently, MATH Domain covers Pre Algebra topics, so, it will mainly be helpful to middle school students, but can also be beneficial to advanced elementary school students, struggling high school students and returning students.

Teachers, tutors, and parents will also find MATH Domain helpful because on top of it being a great learning tool, it also makes for a great teaching tool.

How will it help?

Learning areas are broken up into small, bite-size, chunks. Many of these “chunks” are followed by a quiz-like area that helps reinforce important concepts (Concept Checks).

Practice areas are also chunked where possible. For example, instead of only providing a practice area for Adding Fractions, there are also practice areas like Finding the Lowest Common Denominator, Finding Equivalent Fractions, and Reducing Fractions because these 3 topics are important sub-topics to Adding Fractions.

What’s the best way to get good at something?

Repetition. Repetition. Competition?

The Practice areas offer an unlimited amount of randomly generated questions for each topic, providing a great brain training workout. One can focus on good accuracy or fastest time and can even submit these scores to compete against others around the world through Google Play’s Leaderboards!

Note to teachers, tutors, and parents

Teachers, tutors, and parents will also find MATH Domain useful. Overall and per-session results are recorded for each Practice section. These results can easily be shared through any messaging program like e-mail. Picture yourself instructing your student (or child) to: “Answer 20 questions from the Practice area, e-mail me the results and attach a screenshot of the Progress Table as proof. I want a minimum of 90% correct by 5:00pm Pacific Standard Time, or you do ten more!” (Just be sure to adjust your expectations to you and your student’s/child’s needs.)

MATH Domain covers the following topics…

BASICS

A. Numbers

B. Decimals

---- i. Place Value

---- ii. Rounding

C. Fractions

---- i. Equivalent Fractions

---- ii. Reducing

---- iii. Lowest Common Denominator

---- iv. Improper to Mixed Number

---- v. Mixed Number to Improper

D. Exponents

---- i. Evaluation

E. Radicals

---- i. Evaluation

F. Absolute Values

G. Conversions

---- i. Fraction to Decimal

---- ii. Decimal to Fraction

H. Inequalities

---- i. Comparisons

FUNDAMENTALS

A. Multiply, Divide, Add, and Subtract

---- i. Integers (positive and negative numbers)

---- ii. Fractions

SIMPLIFYING

A. The Order of Operations

---- i. PEMDAS

If you don't see a topic you're having trouble with, check back some other time. (Although, MATH Domain currently covers Pre Algebra topics, the goal is for it to go over Algebra I topics as well.)
