When a kid in Reddit user dimetri's class was caught using his phone in math class, the teacher seized it, set a new pass code and then gave him this note to figure out the new code. That's one way to impress the importance of math skills on to your kids.

At 10% factor multiply by 1.11111
rounds to $1200 added to both cars
$21,800+$1200=$23000*.1=$2300
$600+$500+$1200=$2300
22% flat of the remainder added in and divided by 48 months...
$23,000-$2300=$20,700*1.22=$25,524/48=$526
$526 rounded to nearest dollar

Only the first one can be found in an hydrogen atom, because it only has one electron. And you need two electrons per orbital.
Each line in the periodic table adds another set of orbitals, in the following order: 1s, 2s, 2p, 3s, 3p, 3d, 4s, 4p, 4d, 4f, etc...
All of these plots are for hydrogen alone; only the first one is the ground state. Larger atoms fill up more than one of those orbitals at a time.
P.S. #3 really don't get the purpose behind this post; it is not a lecture in physics -- it is a BATCH OF COOKIES
