Standard: Use the correct order of operations to evaluate algebraic expression such as 3(2x + 5)^2.

 

Student Friendly Language:  I can solve an expression using P.E.M.D.A.S.

 

 

P: parenthesis

E: exponets(powers/roots)

M: multiplication

D: division

A: addition

S: subtraction

 

 

 

 

Exemplar:

 

 

      2+7(3*2)+7(9+4)

 

 

1.You will first do the expression inside the parenthesis starting from left to right.

 

         2+7(6)+7(9+4)

 

2. Now solve the other set of parenthesis to simplify the expression.

 

        2+7(6)+7(13)

 

3. Now multiply 7*6 because it is the first set of numbers that you will see from left to right.

2+42+7(13)

 

4.Evaluate the other set of parenthesis.

 

2+42+91

 

5.You will now add 2+42.

 

44+91

 

6.Lastly, solve your last expression.

 

135

 

7. You're now done with your problem.
