Description

From the listing uploaded by “catappult”.

Decimal Math is designed to teach student how to work with positive and negative decimal number (ex: 2.43 + 3.21 or 34.43 ÷ 4.33). It contains several topics: addition, subtraction, multiplication, division. Each of them has 5 subtopics. The first one is the introduction which gives you a overall of what you are going to learn in the topic. And then, base on a specific level, you would have 2 or 3 examples. Next you will have a chance to practice by doing the exercises. When you have mastered with it, you can check your knowledge with the quiz. After completing all of the levels you may do the test to see how well you understand the topic and if there are some missing part that need to be reviewed. As mention earlier that examples, exercises, and quiz are divided into levels. There are several levels in one topic. The first one would be really basic. It helps student easily get into topic. When they move to the next level, they will have to apply what they have learned in the previous one to solve the problem. The final level will be a review. It contains the problem from all of the previous levels.

Can I install this APK over the version I already have?

Is the Decimal Math APK safe?

No one can promise that a file is safe, but some things can be checked. The source store rates this file Trusted. After downloading, check that the file's MD5 is b15e32dc7ae086be7deda83f71fdd870.
