THANK YOU!!!
you are the only person who has helped me at all with negative and positive numbers!
(i just really dont get the point of negative numbers when you can have positive numbers instead, which are also a whole lot less complicated)
thanks Sal Khan! my dad really likes your work too.

How do I make a formula to give me a percentage change that will always be correct. For example: a company's EBIT grows from -2 to +5. Or from +5 to -2. Just doing a simple division and subtracting one will give me the wrong answer in the first case. How do I make a generic formula I can copy across a row and not be affected by this. Thank you!

good educational videos...but its better to use ''unknown'' number rather than ''undefined'' it more easier to understand ;]

So i can imagine the multiplication of a negative number (aka if the hole was three times larger how large would it be) in the same ballpark i can imagine a negative number being divided by a positive number (aka if the hole was half as big how big would it be.) but is there a multiply Appels example of dividing a positive number with a negativ number?
I can of course accept the logic of the minus being carried but i have a hard time imagine what that would look like.
