I was struggling with school due to personal problems and didn't pay attention or care about my grades, now I gotta catch up in order not to fail. These videos help me out a lot, thanks man.
This video SAVED me…. I just moved across the country and got thrown into this with absolutely no idea what the hell was happening, then school got shut down because go snow so I’m teaching myself how to do this thank you so much
great lecture! in your last example i need you to explain why u chose to move the X from the right to the left? If you would have moved the other X from left your answer would have been wrong , why is that????
Why does the < flip when you multiple or divide by a negative number? You said it's not necessary for us to know but I want to know because it improves my understanding about inequalities and mathematics in general.
As variables don't want to be negative alone in inequalities like the radicals don't like be in their form in denominators,we multiply or divide with negative sign and flip inequality symbol to make it positive.
