  1. why do you use PEMDAS? what’s the conceptual reasoning behind it? i mean just because you say PEMDAS, are we supposed to take that as a fact? why not SADMEP? or PMDEAS? what’s the conceptual reasoning behind that order… not knowing that makes math less of a logical process than understanding the reason behind it.

  2. Can anyone help me with the first order of operations. My professor said that in old textbooks there is a first order of operations that is not groups or parentheses. Not sure what it is and could not find it on the web. He also said it is not functions. Please help anyone.

  3. 7+3=9 but it’s in brackets so wouldn’t it stay in brackets in the equation and then that would make it 7×2+(16)÷4×2?

  4. ( says nice VERY sarcasticly ) nicccceeeee ( the only reason I watched this was cuz my teacher told me to )

  5. guess i got it since i was able do the answer in my head in 15 seconds thanks to you my man, thumbs up
