    Just checking in and giving my eternal thanks for making all these videos over the years. I watched your videos from my first pre-algebra college class all the way up to when I started differential equations. I don't know how I (and so many other stem majors) could have done it without you. Thank you sir!!

    • @idkwhatusertoput8476
      @idkwhatusertoput8476 4 роки тому

      Was thinking the same thing! I thought i would be wrong for doing so but apparently you can do one or the other?

    • @zlcoolboy
      @zlcoolboy 2 роки тому

      Yeah, normally you divide though. (-1)(-3)=3 and (-1)(-y)=Y. Since the same thing is happening on both sides, then it's legal. Its faster to write a division than multiplication, so it makes sense that it is not normally done this way.

    I know how to solve all variables of all equations at once. first I spray lighter fluid all over the equations second I strike a match and whalaah no variable and no equations, problem solved.
    Some people say Pie cant be solved or simplified. I say nonsense you buy me a pie from Perkins and I will be happy to simplify and or solve that problem too.
