You can click the integral to change it into "d/dx ()," and vice versa. You can click each variable to change its value. It's a LOT of coding, so I hope you like it! Also, you can hover over each sprite and press the key of that to make it speak its value. Or you can also press "R" to make it sound like a whole crowd said it!
I used 281 blocks to make this project, only four sprites. The stage is empty. Integral/Derivative has 158 blocks. The other sprites have 41 blocks EACH.
