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.
