I need help with order of operations please! Offering medals for best answer, thanks. 4+8x5÷4

OpenStudy (ja1):

PEMDAS

OpenStudy (anonymous):

What?

OpenStudy (ja1):

Parenthesis Exponents Multiplication Division Addition Subtraction But you only need to worry about the MDAS part

OpenStudy (ja1):

So first you Multiply

OpenStudy (ja1):

\[4 + 8 \times 5 ÷ 4\]

OpenStudy (ja1):

8 * 5 = ?

OpenStudy (anonymous):

40

OpenStudy (ja1):

Yes so: \[4 + 40 \div 4\]

OpenStudy (anonymous):

14

OpenStudy (ja1):

well no, \[40 \div 4\] is not 14

OpenStudy (ja1):

Think of it this way, if you have 40 cookies and 4 kids how many cookies does each kid get?

OpenStudy (anonymous):

10

OpenStudy (ja1):

Perfect :D So now do the A part

OpenStudy (ja1):

\[4 + 10\]

OpenStudy (anonymous):

14

OpenStudy (ja1):

Perfect :D so since there is no subtraction you are done, your final answer is 14, so do you understand all the steps I showed you?

OpenStudy (anonymous):

Yup! Thank you! :D
