PEMDAS P.E.M.D.A.S

By Julie Malicious

Why do we use pemdas? PEMDAS is an acronym used to remind people of the order of operations. This means that you don't just solve math problems from left to right, rather, you solve them in a predetermined order that's given to you from the acronym PEMDAS.​

So why do we use P.E.M.D.A.S?​

​

​PEMDAS is an acronym that stands for...

Parenthesis

Exponents

Multiplication

Division

Addition

What does PEMDAS EVEN MEAN?!​

​

P-lease

E-xcuse

M-y

D-ear

A-unt

S-ally​

​Some text here about the topic of discussion.

SO HOW CAN I REMEBER THE EXACT ORDER?​

​

Ready?​

NOW LETS SEE IF YOU GOT THE HANG OF IT!

Multiple Choice

( 3 x 2 ) + 4 =

What should I do first?

• ( 3 x 2 )

• + 4

• None of the above

Multiple Choice

Kate and Devin both solved the same problem shown on the last question

( 3 x 2 ) + 4 =

Who answered correctly?

( Work the problem out on a sheet of paper! )

• Kate:

  ( 3 x 2 ) + 4 = 10

• Devin:

  ( 3 x 2 ) + 4 = 9

​Some text here about the topic of discussion.

If you answered the last question incorrectly use and remember th​is strategy

​

​If you're still a bit confused listen closely.

The first thing I did was add 3+1, I did that because 3+1 was in parenthesis and as you should know by now we always do parenthesis first. We all know 3+1=4, since we saw that their is a x4 next to it we have to.... that's right​! We now do 4x4 = 16!
