Now, let's talk about the block that we use for

numerical catalysis in this example extension clearly add padding and

this draw and drag padding into my application

[MUSIC]

Then I'm going to set up the blocks for my example.

In this example I'm going to be using this block.

When Button 1 is clicked I'm going to ask my app to set the text of the button

to something else, and then something will be calculated using a math equation.

If I want to do any calculations I have to use the math blocks

which are in blue color.

And I'm going to use this block for addition, and

this block for multiplication.

And then I will need three numbers.

So I'm going to create this number and then I going to Duplicate,

because I need three numbers.

Then I'll change that to 1, 2, and 3.

Okay, I will add up 1 and 2 and

then multiply the result of this summation by 3.

So it's like 3 times 3 so the result will be 9.

Now, let's run this example on emulator.

In this example app, if you click on the button, the name of the button we

changed to a number, and the number is calculated using a math equation.
