This is an explination of the scratch supported formula abs (download to use the messing around with abs part, and also it looks weird and a bit missplaced beacause of the website size change and stuff)

I already knew the area of a square part, ya know how to find areas of circle and triangle?
(view all replies)Comment Reply
Circle: Pi*radius*radius OR Pi*r^2 (pronounced "Pie are squared" (no, pie are round!)) Triangle: (b*h)/2 (b = base, h = height; the base is the bottom part)

abs is not a formula, it's a function. Like +, -, *, and /. It exists not just in Scratch, but in real math as well. As my math teacher taught me, "The absolute value (abs) of a number is it's distance away from zero in integers." So yes, it does turn a negative into a positive, because, for example, -5 is (1, 2, 3, 4, 5) integers away from zero. As is 5, (1, 2, 3, 4, 5) integers away from zero. Get it?

I have never understood why people invented ABS. It's pointless (right now in my 7th grade eyes)

The are of a square is length x 4! Silly, well actually both work. Or even width x 4.

Actually, that's perimeter. Area would be (where s is the length of a side): s^2.

even though I already know what abs stands for (absolute value) i think that this would very much help people understand this concept. good job!
