Question 1204585
<pre>
Then please re-learn PEMDAS.  And, be sure to learn that there are two flaws in
it.
  
<font size=5><b>P</b></font>
It says to complete first what's inside any parentheses "( )", 
until what's inside them becomes a single number, then erase the parentheses and
write it as a single number.

Then do the same with brackets "[ ]".
Then do the same with braces "{ }".

<font size=5><b>E</b></font>
Then complete any exponents.

<font size=5><b>MD</b></font>
Then go from left to right, and when you come to either a multiplication or
division, whichever comes first, going left to right, complete it and replace it
by a single number. 

<font size=5><b>AS</b></font>
Then go from left to right, and when you come to either an addition or
subtraction, whichever comes first, going left to right, complete it and replace
it by a single number.

<font size=5><b>FLAWS</b></font>
The first flaw of PEMDAS is that the "MD" misleads some people to believe
multiplication always comes before division, which is false, because it's
whichever comes first going left to right.

The second flaw is similar. the "AS" misleads some people to believe addition
always comes before subtraction, which is false, because, like multiplication
and division, it's whichever comes first going left to right.  

Be sure to do the M's and D's before doing the A's and S's. <font face="wingdings" size=4>J</font>
