Aright guys, so this is my buddy Festus and he is stressed out, look at that look on his
face like intensely stressed out right now cos he can’t remember his math formulas
for his math class so I’m going to show you and my friend Festus how to memorise math
formulas and hopefully this dude will chill out a little bit.
Now I’m going to turn this this way. Ok so the reason Festus has a hard time memorising
his math formulas and the reason most people do is they just seem non sensical or they
seem hard to memorise and they are but if you break them done into picture there not.
Let me show you what I mean. Let’s take the volume formula for a sphere.
Volume formula for a sphere is four thirds pie r cubed.
Take another one. The area formula for a parallelogram and I’m just going to abbreviate cos this
marker does misspell sometimes so parallelogram base times height and a area formula for a
circular ring, that two pie p w. So no matter what math formula you’re trying
to memorise, Festus is trying to memorise algebra or geometry formulas like this, or
maybe you’re a stock broker needing to memorise formulas, your any kind of student and you
have formulas in physics, whatever, one thing that you’re going to find common in all
math formulas, there all going to have variable in them that repeat. A variable is simply
a letter normally, a variable is simply a letter for an unknown number. So here r which
stand for radius unknown, b stands for base, h stands for height, p stands for perimeter,
w stands for width, these are the variable, these are unknown numbers. The first thing
you need to do when your memorising math formula is you need to take a look at all the formulas
as a whole and you need to see what the variable are. So right here we have r, we have b, we
have h, we have p, and we have w. then after you have your variables list it out like this,
simply go back and create pictures for all these variable. For example every r I’m
going to say is going to be a rat. Every b is going to be a b like a bumble bee, every
h is going to be a hat, like a cowboy hat, every p is a pirate, and every w is a window.
So now we have our variables, so if you’re looking at your math formulas the first thing
you do is you go and look at all the variables then you create pictures for the variables.
R is a rat, b is a bee, h is a hat, for me p is a pirate and w is a window. After you
have your variables creates then it’s simple its really simple you just go back and you
make stories, every math formula isn’t a math formula anymore it’s a story and stories
are easy to remember. Ok so let’s take this formula first, a parallelogram,
base times height. We’ve already said that b is a bumble bee, this is my bumble bee outfit,
and h is always a cowboy hat. So this is the picture that I want you to imagine.
So for this one, we got a parallelogram equals base times height. Here’s my bumble bee
outfit, bumble bee wearing a hat, bh. Imagine there some parallel bars here, some gymnastics
parallel bars and this bumble bee starts doing gymnastics on the parallel bars.
God, I think I’ve pulled a muscle, ok that’s good enough.
Alright, the area formula for a circular ring is two pie p w. for p we use a pirate, for
w we use a window, and for two pies we’ll use two pies. So imagine this, imagine a pirate
in a window, he’s wearing a circular ring and he’s eating two pies. the area formula
for a circular ring is two pie, is two pie p w. it’s as easy as that.
So the next one is the volume formula for a sphere. A sphere, here’s a sphere, the
volume formula for sphere is four third pie r cubed. The way we remember this a sphere
and the equator is around the centre, your have four continents on top and three on bottom.
Some might overlap but just for the purposes of this say there’s four on top and three
on bottom. You have a sphere, four continents on top, three on bottom. On top of the globe
I want you to imagine a piece of pie and its getting eaten by a rat. The rat is frozen
cos it’s the North Pole, so a sphere is four thirds pie, r for rat, and he’s frozen.
Sphere equals four thirds, pie r cubed. So folks that’s how you memorise math formulas.
The first thing that you do is you go through and you pick out all the variables. You decide
r is going to be a rat, b is going to be a bumble bee, h is going to be a hat, p is going
to be a pirate and w is going to be a window. And then after you do that, after you have
all the pictures for your variable done you go through and create stories, sphere is four
third pie r cubed. Parallelogram, the area formula for that is a b times h , b h, bumble
bee and a hat is what we use, circular ring is two pie pw. It’s as simple as that. My
buddy Festus is totally chilled out right now, he’s got his math formulas down, he’s
going to ace his test, he still looks serious but he’s just a serious dude. I look forward
to seeing you on the next video.
