[(3 + 5) • 2 – 5] • 3 What is the value of the expression?

OpenStudy (smartanne):

I can help

OpenStudy (anonymous):

Would I use P.E.M.D.A.S?

OpenStudy (smartanne):

Yes

OpenStudy (andrewishere):

So what you want to do first is what is in the brackets. But in those brackets are parentheses, so do what is in those (3+5)

OpenStudy (andrewishere):

Then use what you suggested P.E.M.D.A.S

OpenStudy (smartanne):

Then multiply that by 2 and subtract 5 from that

OpenStudy (smartanne):

Then multiply that by 3

OpenStudy (anonymous):

8

OpenStudy (andrewishere):

Correct

OpenStudy (andrewishere):

Now multiply that by 2

OpenStudy (andrewishere):

(8*2)

OpenStudy (anonymous):

16

OpenStudy (smartanne):

yes

OpenStudy (andrewishere):

Good. Now subtract 5

OpenStudy (anonymous):

11

OpenStudy (andrewishere):

Excellent. Now multiply it by 11

OpenStudy (smartanne):

Now multiply by 3

OpenStudy (andrewishere):

Sprry by 3

OpenStudy (andrewishere):

(11*3)

OpenStudy (anonymous):

33

OpenStudy (andrewishere):

And that is your answer

OpenStudy (smartanne):

correct

OpenStudy (andrewishere):

Congrats

OpenStudy (smartanne):

Medal if we helped :)

OpenStudy (andrewishere):

Does the P.E.M.D.A.S process help you?

OpenStudy (anonymous):

Yes. I can only give one medal though :(
