LOL - well, not really. I am a public school teacher in the US, and rules of operation always state multiply/divide before add/subtract. Actually, it's this order:
brackets
exponents
multiply/divide
add/subtract
and always from left to right inside each order.
Using the symbol "x" is most common when hand printing, but on calculators or computers, you would use "*" to indicate multiplication, since it is a mathematical symbol. A computer wouldn't know what to do with an "x" in the middle of an equation!
And now you have your mini math lesson for the day, just in case you ever get called to play "Are you smarter than a fifth grader"!
