<span><span /><span>The answer to that problem is
813. When you are given a problem like this, you can answer it by using the
MDAS technique. MDAS stands for multiplication, division, addition, and
subtraction. Since you are following the MDAS technique, you are asked to answer
the equation based on MDAS order. To put this simply, look at the example
below:
20x40+3x9/3+4
800+3x9/3+4
800+27/3+4
800+9+4
809+4
813</span></span>
You can clearly see the MDAS order by following the bold
