Evaluate 32 + (5 − 2) ⋅ 4 − 6 over 3

OpenStudy (anonymous):

3^2

pooja195 (pooja195):

\[\huge~\rm~3^2 + (5 − 2) ⋅ 4-\frac{ 6 }{ 3}\]

OpenStudy (anonymous):

yes, I couldn't figure out how to set it up like that aha

jabez177 (jabez177):

First step is Parentheses. What is 5 - 2?

OpenStudy (anonymous):

3

pooja195 (pooja195):

\[\huge~\rm~3^2 + (3) ⋅ 4-\frac{ 6 }{ 3}\]

pooja195 (pooja195):

3^2=?

OpenStudy (anonymous):

6

pooja195 (pooja195):

3^2=3*3

OpenStudy (anonymous):

wait its 9

jabez177 (jabez177):

Now exponents. What is 3 x 3? 3 x 3 is the same as \[3^{2}\]

OpenStudy (anonymous):

so its 9

jabez177 (jabez177):

Now multiplication, what is 3 x 4?

OpenStudy (anonymous):

12

OpenStudy (anonymous):

so now its 9 + 12 - 6 over 3 right?

pooja195 (pooja195):

\[\huge~\rm9 + 12-\frac{ 6 }{ 3}\]

jabez177 (jabez177):

Actually we do 6 divided by 3. That's what that fraction means. :)

OpenStudy (anonymous):

so 9 + 12 - 2

jabez177 (jabez177):

Yeah, addition comes first.

pooja195 (pooja195):

\[\huge~\rm9 + 12-2\]

OpenStudy (anonymous):

is the answer 19?

pooja195 (pooja195):

Yes

OpenStudy (anonymous):

okay thank you both :)

jabez177 (jabez177):

You're welcome! :D

pooja195 (pooja195):
