How do you remember things?, formulas, vocabulary, short cuts, etc? Options

[*My Cinderella.*]

SOHCAHTOA, counting 9 fingers, (a + b)(a - b), and all that jazz. When it comes to memorizing words and formulas, how do you keep them in your head?

For example, if I wanna know what direction I'm going in. (North South East West) I'll always start from the top and go clockwise saying: Never Ever Smoke Weed.

What are some of your methods to short cuts and such?

How could I forget PEMDAS, Please Excuse My Dear Aunt Sally.

oh my. i've used that one so many times.
in chemistry, when we memorized the elements i always got the symbols for gold and silver confused. so i remembered gold to be au and silver to be ag for "'aint gold".
i also made up the following.
iron:fe:frank ater[i imagine a frank hotdog on an iron pole]
tin:sn:add an i and it rhyms
mercury:hg:hot gasses
potassiam:k:the potty's ok
i make up odd things.
i remember my planets by a blue's clues song. haha.
lyrics:
well, the sun's a hot star and mercury's hot too. venus is the birhgtest planet and earth's home to me and you. mars is the red one and jupiter's most wide. saturn's got those icy rings and uranus spins on it's side. neptune's really windy and pluto's really small. well, we wanted to name the planets and now we named them all.
let's see....what else.
oh yeah. i remeber this atom song called the adom's family that went to the tune of the adam's family theme song.
lyrics:
1st Verse:
They’re tiny and they’re teeny,
Much smaller than a beany,
They never can be seeny,
The Atoms Family.
Chorus
2nd Verse:
Together they make gases,
And liquids like molasses,
And all the solid masses,
The Atoms Family
Chorus
3rd Verse:
Neutrons can be found,
Where protons hang around;
Electrons they surround
The Atoms Family.
Chorus
Chorus:
They are so small.
(Snap, snap)
They’re round like a ball.
(Snap, snap)
They make up the air.
They’re everywhere.
Can’t see them at all.
(Snap, snap)
