PEMDAS REVIEW

PEMDAS

• Parenthesis

• Exponents

• Multiplication/Division (in the order they are seen in the problem)

• Addition/Subtraction (in the order they are seen in the problem)

Multiple Choice

What does the "P" in PEMDAS stand for?

• Plus

• Parenthesis

• Place

Using PARENTHESIS

• ALWAYS work the parenthesis first in a math equation.

• EXAMPLE

• 45+(20-5)

• 20-5 is done FIRST because it is in the parenthesis THEN the rest of the problem is worked.

• The answer would be 30

Using EXPONENTS

• An exponent is a numbe that is multiplied by itself multiple times.

• EXAMPLE

• 2⁴

• This is read as "2 to the 4th power"

• To work this out you would multiply 2 to itself 4 times

• 2 x 2 x 2 x 2

• 2⁴=16

Multiple Choice

How would you solve this problem: $$3^4$$  

• 3x4

• 3+4

• 3x3x3x3

Multiple Choice

What does the "E" in PEMDAS stand for?

• Equal

• Equation

• Exponent

Multiple Choice

What does the "M" in PEMDAS stand for?

• Multiply

• More

• Minus

Multiplication/Division

Multiple Choice

What operation do you use to answer this problem: 2(5)

• Addition

• Division

• Multiplication

Multiple Choice

What does the "D" in PEMDAS stand for?

• Divide

• Dozen

• Dime

Multiple Choice

What does the "A" in PEMDAS stand for?

• Addition

• Any

• Above

Multiple Choice

What does the "S" in PEMDAS stand for?

• Square

• Scale

• Subtract

Addition/Subtraction

• The LAST operations to be done in the order of operations are addition and subtraction.

• Like MD, these are done in the order they are seen in the problem from left to right.

• EXAMPLE

• 55-5+10=

• 55-5 is done FIRST to get 50 then we add 10 to get 60
