Algodoo

Very confusing! Where is the "uncovered input block" that you mentioned?

Suggestion: Put a label with an arrow that points to the input block so that people can easily locate it without having to guess where it is.

will do! it was pretty late and i was tired.

Okay, now I get it!

More suggestions:
1. Never assume that other users know what you know. When you make a complex scene which is not self-explanitory, you must show some instructions. And you can't simply write "enter numbers 0 - 3" but you have to explain HOW to enter the numbers. In this particular scene, I did not know that I had to change the text from 0 to some other number, and then click on the box! I finally figured it out by myself but you could have saved me some time by explaining it in the scene!

2. The Algodoo clouds are always in the scene because they show up by default. For scenes in which clouds make no sense (such as this scene here) you should disable the clouds because they are very distracting. Clouds can be disabled in the "background" edit page.

Besides those minor things, you did a great job on the scene overall!

I feel like this is more complicated than it should be for such a simple task, I may be wrong though

It's supposed to be complicated. After all, this is Algodoo... It's not a five dollar calculator made in China.

There's nothing wrong with a five dollar calculator made in China. If a five dollar calculator can calculate as good as a twenty dollar calculator then the five dollar one is a better calculator.

I'm just saying that with the technology used here being nikoki's calculator blocks there's probably a more efficient way to do the same thing. I'm sorry if that's rude, I didn't mean to detract from the effort you put into this scene, I just wanted to encourage you to further optimize it.

one of the calculator blocks is cut in half
