'Order of Operations' Music Video - (A Math Parody of 'Bad Guy' by Billie Eilish)

Показать описание

In this music video, Mr. Almeida explains some misconceptions about the order of operations and offers some helpful strategies to evaluate numerical expressions. He also settles the debate on the Internet that had everyone getting either 1 or 16 for the expression 8÷2(2+2).

Here are the lyrics in long form:

So recently, there was this debate on the Internet
that had everybody talking,
trying to figure out
what the value of an expression was.

So let's go through the order of operations,
and figure out what the value truly is.

In math we have these things called expressions,
numbers with operations, and
if we want to find their values,
we must follow

certain conventions
that will help us come to the same value,
so we won’t be getting different responses
and be confused.

Now you’re evaluating numerical expressions,
and you’ve got this obsession
with order of operations.
You may have heard
of this thing called PEMDAS,
but please leave it in the past
or you might be misled
to the wrong value.
(Ugh!)

Listen closely.

One thing you may find helpful
is to write the order you will go in
above the expression
so you'll know what you will do.

First look for grouping symbols.
They tell us to do that operation first,
and if you see groups inside of groups,
start with the innermost.

From there we look for exponents.
Then we multiply and divide
from the left to the right.
You will see that
terms are only left,
so you add or you subtract
from the left to the right.
