# Math extension (for learning propose) - My first extension [FREE]

### Write a short description

Math extension - my first try to make extension.
I put on it several basic tools, like calculate BMI, take the big number from two numbers, and more…
Update: I splitted several tools to another extension. the link to another post will here in one week.

### Add a picture of all the blocks

Blocks:

Method AreEquals - boolean.

Method WhoBig - integer or double, its up to you what you put inside.

Method BMI - double number.

Method Square - integer or double.

``````All this are return methods.
``````

Now the void methods with the events:

Event for QuadraticEquation (CalculationDone) - two double numbers (answers varible is list, x1 and x2 are double numbers).

Event for CircleCircumference (RadiusDone) - double number.

### Write instructions to use your extension

Simply, how to use?
take block, and attach it to set label1.text, or toast notification with notifier, etc…

Its my first try, and I have inspired by @Ken in his post https://community.appybuilder.com/t/my-first-extension/6277

I want to say thanks to @Mohamed_Tamer for helping me at all the process of understanding how to make extension, and undersnad how to write java correctly.

Just so everyone knows, BMI is often not accurate because it does not take muscle into account.

That’s true. BMI works best for people with no excess muscle that comes from manual labour or working out.

However, that’s not a criticism of this extension, just of the measurement itself.
