how do I write a mathematical phrase or sentence...

OpenStudy (anonymous):

Think of something in your real life that spend money on or have something to do with numbers.

OpenStudy (anonymous):

You buy something and pay some money and get change back? Anything like that can be easily written as a math problem.

OpenStudy (anonymous):

Oh ok.. thank you GT..I have been trying to think of how to write one, can you give me an example? if you don't mind

OpenStudy (anonymous):

I bought a cup of tea at Starbucks today. It cost me $2.65. I gave the cashier$10. How much change did I get back?

OpenStudy (anonymous):

or how about one that pertain to algebra. I have to take intermediate algebra, and I have never taken algebra ever in my life. online schooling, college, ugh.

OpenStudy (anonymous):

Well, let us think of a business problem then. It costs Starbucks $0.50 to purchase tea bags. They sell tea at$2.65 per cup. How much profit do they make per day?

OpenStudy (anonymous):

cool...thank you bunches. So you know how to do intermediate algebra?

OpenStudy (anonymous):

I can always try. It has been 25 years. :-)

OpenStudy (anonymous):

i been out of school for 25 years, and back then, school was basic, nothing like what kids learn nowadays.

OpenStudy (anonymous):

Was there another problem you needed help with?

OpenStudy (anonymous):

not sure if you can help, but here is another one I need to do: 1. What are the steps of the order of operations? 2. Why is it important that you follow the steps rather than solve the problem from left to right? 3. Write an expression for your classmates to simplify using at least three of the following For example: -42 + 5(-3) - 8 Groupings (parenthesis, brackets, or braces) Exponents Multiplication or division Addition or subtraction

OpenStudy (anonymous):

this my my first week of class, and these Discussion questions can be confusing..its harder to do math online with no face to face interaction...i struggled in math.

OpenStudy (anonymous):

you have the "order of operations" written down under 3. so that is the answer to your first question

OpenStudy (anonymous):
OpenStudy (anonymous):

if you solve for example $2\times 3^2$ from left to right you would say $2\times 3=6, 6^2=36$ but the correct way is to use compute the exponent first and write $3^2=9,2\times 9=18$ that is one example of where you cannot work from right to left

OpenStudy (anonymous):

so that is how i would put my order of operations>

OpenStudy (anonymous):

ok...thank you Satellite and GT for the site..

OpenStudy (precal):

We also, use PEMDAS to remember order of operatio. Please Excuse My Dear Aunt Sally P is () always do what is inside the (), sometimes we have to do the order of operation inside the () E is exponents M is multiplication and D is division Always do these left to right together A is addition and S is subtraction Always do these left to right together example 8/4*3 do division first then multiplication 8/4 is 2 2*3 is 6

OpenStudy (anonymous):

thank you bunches precal..i will copy and paste for my notes.

OpenStudy (precal):

There are also, cool websites to play games using order of operation. Google interactive math games + order of operations. If you can't find any let me know I will submit some sites.

OpenStudy (anonymous):

I have the site to khan Academy that is helpful, its just when it comes to my online discussion questions, its hard for me understanding what they are talking about and how to write out the problem...
