GEMDAS

P.E.M.D.A.S
or
G.E.M.D.A.S

Work together to find the true meanings of PEMDAS and GEMDAS and uncover the difference between PEMDAS and GEMDAS.


Then, we will work out PEMDAS and GEMDAS problems and figure out how to identify PEMDAS and GEMDAS problems.

Learn about PEMDAS and GEMDAS and what they mean. We will...

P.E.M.D.A.S or G.E.M.D.A.S...?

P.E.M.D.A.S or G.E.M.D.A.S can both be used to figure out a math problem.

E X A M P L E:

What does P or G stand for?

P is different from G because..

P is Parenthesis, which are THESE little guys right G is groupings, which are THESE little guys

( a n d ) ( and ), [ and ], and finally { and }
which means that parenthesis are only one pair OF groupings

Multiple Choice

Ellie Gune is a 4th grade girl who is 2 grades ahead in math!

But...on a 6th grade math placement test, she has to figure out this problem:

"..7*2 + 4-3 *5.."

What is wrong with this problem?

• It has no groupings of any kind to tell what to do first

• It is too long to be a math problem

• There are more odd then even numbers

we know P is Parenthesis but what are the rest?

• exponents

• multiplication

• division

• addition

• subtraction

G is... GROUPINGS

P is... PARENTHESIS

Both mean almost the same thing!
