  Enjoy the egg on your face bud

  None on my face. My students do very well in their tests. How about you? BTW try it on a calculator and guess what answer you’ll get. hint: it’ll be the same answer regardless of which order you do it 😂

    10-1+1=10 only if you don’t the addition first 1 + 1 = 2 - 10 = 8, which was my mistake, which I already stated.

    Now jog on “math teacher”.

      10-1+1=10 only if you don’t the addition first 1 + 1 = 2 - 10 = 8

      Nope, gives 10 in any order. 10+1-1=11-1=10 <== addition first. Accountants would have a nightmare if order mattered.

      which was my mistake, which I already stated.

      No, your mistake was adding brackets, 10-(1+1) ISN’T how to do addition first. 10+1-1 is. Ask an accountant! 😂

      I see you still didn’t try it on a calculator yet then

        Nope, yet again you just did 10-(1+1), which is wrong for 10+1-1. It gives 10 in any order. 10+1-1=11-1=10 <== did addition first, got 10. Accountants would have a nightmare if order mattered. “Did we receive this payment first, or this invoice? The order matters! ARGH!”

        I know it is wrong, which is why I am telling you what my mistake was originally. The fact that you still don’t get it demonstrates your complete lack of understanding.

        Order does matter, and that order is left to right. My mistake was doing the addition before the subtraction when the equation reads 10 - 1 + 1.

        How are you still not getting this?

        No, your mistake was adding brackets, 10-(1+1) ISN’T how to do addition first. 10+1-1 is. Ask an accountant! 😂 As you discovered 10-(1+1)=10-1-1, which isn’t 10+1-1, nor 10-1+1. 10-1-1=8, which is what you did - 10-1-1=10-(1+1) - 10-1+1=10, 10+1-1=10.

        No it wasn’t. The original equation is written correctly but the logic is incorrect because in order to make it work the way I declared you have to do the equation x - y + z doing the y + z first (which was the mistake doing addition then subtraction instead of addition and subtraction in order from left to right.)

        I see you still didn’t try it on a calculator yet then

        I see you are still being a bad teacher who refuses to listen, so I am not continuing with you. The fact that you still don’t get it demonstrates bad faith, willful ignorance, and an unwarranted superiority complex.
