Is that a snapshot of your forehead?

I'm just old and took high school math like 100 years ago!
The order of operations is PEMDAS, which stands for Paranthesis, exponent, multiplication, division, addition and subtraction.
I got several of these wrong myself, but this one was simple. You do multiplication first so 10x0, which is 0+10=10,
QED
Anyone wanna discuss other math problems? I'll start off by posting this one,

There were several posted in the thread already (Daredevel, PFH and I have each posted at least one, iirc), if you want to try your hand at those.

Don't insult us.
Okay, fixed my problem. Now with variables that don't suck and correctly solved in my handy-dandy Notebook++!
Okay, here's a new problem, since I just learned a new type of math:
On a given stretch of highway, 2125 vehicles travel every hour per lane and 25 vehicles travel every mile per lane. To try and reduce the speeding, a police cruiser enters the highway in the left lane and travels the speed limit (65 mph) for a 15 mile stretch of the highway, and then exits. While doing so, no drivers are willing to pass the cop in any lane, and the traffic increases to 30 vehicles every mile per lane.
By the time the cop exits the highway, how much congestion has the cop introduced into the highway behind him/her? (Answer should be in vehicles.)
Sigh..... this type of problem always throws me off because it's so.... open ended. Do we take account of the transition from 25 vehicles to 30 vehicles per mile per lane? Or the chain reaction traffic caused by the congestion in that 15 mile stretch? Too many questions!
Don't tell me we have to use Diff Screw (Eq) for this problem...
Oops.. I kinda assumed everyone went to high school.
Discrimination on my part?
That is because you are still very close to high school age.
Uhhh no, adults do really advanced stuff that high schooler can't such as analytic algebra, exponential geometry, etc...
Kaczynski could for example.
Yeah, and he decided to bomb a few people just for laughs, too.
I had completed Trig, and Calculus before 9th grade. Due to state requirements, I had to repeat classes even though I aced the classes. In 11th & 12th grades they brought over math courses from the Jr. College.
