Answer:

Here's an example scratch program for finding the sum of two numbers.

Explanation:

First, drag and drop two "ask" blocks from the “Sensing” category and place them below the “when green flag clicked” block.

Change the prompt text on both ask blocks to "Enter a number" and "Enter another number".

Drag and drop a "set" block from the “Variables” category, and change the variable name to "num1". Place it under the first "ask" block, and set its value to "answer".

Repeat step 3, but change the variable name to "num2" and place it under the second "ask" block.

Add a "join" block and connect it to a "set" block.

Inside the "join" block, type in "sum:" followed by a space.

Drag out the "num1" variable block and place it next to the colon in the "join" block.

Add a "+" operator block and place it next to the "num1" block.

Drag out the "num2" variable block and place it next to the "+" operator block.

Finally, drag and drop a "say" block from the “Looks” category, and connect it to the "join" block.

Here is what the final program should look like:

when green flag clicked

ask "Enter a number" and wait

set num1 to (answer)

ask "Enter another number" and wait

set num2 to (answer)

join "sum: " (num1 + num2)

say [result v]

When you run this program, it will prompt the user to enter two numbers, add them together, and then display the sum as "sum: [result]" where [result] is the actual sum of the two numbers.

In the « Costumes » tab, click the « Import » button to import a new costume for the sprite. You can use an image editor to create your own costume, or you can choose a costume from the Scratch library. In the « Scripts » tab, drag out a « set costume to [costume] » block and select the costume you want to use from the dropdown menu. You can then use this block to change the costume of the sprite when certain events happen, such as when the sprite is clicked on or when a key is pressed. For example, you could create a script that changes the sprite’s costume every time the space key is pressed: Drag out a « when flag clicked » block and add a ...
