• Anyone who agrees that Khan Academy is the best math learning program in the world, upvote this post.
if 0x1 = 0 then 0/0 = 1?
whole number divided by itself is equals 1? even if that number is 0? why?

• Not quite. Anything divided by 0 is undefined. To follow your logic here, 0x2=0 so 0/0=2. Because we have multiple possible answers, it is undefined.
• at first, it wasn't clear. so i watched the video 3 times and then everything was clear. it was as if i had something covering my eyes.
thank you, Sal
