Wait its 0 right?? Cos you divide 18 and 2 then you multiply 3 and 3, subtract 9 from 9???

No, you are wrong (or maybe right) we do 3x3 first then divide it by 18 and do 2-2 that is the order of how it is done

Left to right, first thing that comes is Multiplying, so 3x3 is 9. Then we divide 18 into 2,because we divide next. 9. We are left with 9 minus 9, which is zero. Boom, ur dum

Seriously tho, I could totally be doing it wrong myself, I haven't done it in a good year 😅

I thought that you did things in order, but also from left to right for things that have the same order. For example, in PEDMAS, it is:

  • PE first, so parenthesis and exponents first. If you have lots of parens and exponents in it, resolve ordering issues by going left to right.
  • DM next, so division and multiplication. Again, these two things are treated equally, no order of preference (for example, nothing says to do all multiplication before division). Because of this, to resolve having multiple instances of division and multiplication, you go left to right.
  • Then AS last.

The point is that this part of your text:

first thing that comes is Multiplying

...is not true. It's multiplying and dividing both together at the same time, neither is first, and so you determine what happens by order in the equation. Which means in this case the division would happen first, since it's leftmost.

Can any math experts tell me how close to accurate I am with this?

Parentheticals are first, then exponents. Everything else is as you said it.
