• Why does he keep saying "Inchrchr chips"
• Sorry so late. Integer chips. They're not really important, just there to help you understand (or it helped me at least). I can't exactly give an example to help because Sal hasn't given that option yet to type integer chips or anything else like that so the only advice I can give is to continue watching the videos and doing the questions and then hopefully you will be able to understand. Hope this helped. Good luck!
• Guys Now I'm confused with brackets of negative numbers
I thought you should add a bracket to seperate only when There are two symbol which represent different meanings
But at , Sal just add an unnecessary bracket on -3+5
Why is that?
• he probably did it because he was trying to explain how the inverse operations can be used to make equivalent expressions or something like that.
