(5.6*10^6)-340,000/2*10^3

OpenStudy (kayders1997):

This is kinda messy so is it (5.6×10^6)-340000/2×10^3?

OpenStudy (kayders1997):

Remember when you do this PEMDAS

OpenStudy (nadiahossain):

\[(5.6\times10^{6})-340,000\div2\times10^3\]

OpenStudy (kayders1997):

Thank you! So do you kbow where to start first?

OpenStudy (nadiahossain):

I did kinda solve and got 2.63*10^4 but I don't think its correct

OpenStudy (kayders1997):

Think about PEMDAS what did you do first?

OpenStudy (nadiahossain):

parenthesis first

OpenStudy (kayders1997):

Yep and what part did you start with?

OpenStudy (nadiahossain):

5.6*10^6 which is 5600000

OpenStudy (kayders1997):

Yes good now?

OpenStudy (nadiahossain):

ummm...I turned 2*10^3 into 200

OpenStudy (kayders1997):

Hmmmm?

OpenStudy (kayders1997):

PEMDAS exponents so you have to do the 10^3 first

OpenStudy (nadiahossain):

yeah and then multiply

OpenStudy (kayders1997):

Wouldn't that be 2000?

OpenStudy (nadiahossain):

oh, my bad

OpenStudy (kayders1997):

And you can't do that step first because when your doing multiplication/division you have to do left to right

OpenStudy (kayders1997):

So you would just have to leave it 1,000

OpenStudy (nadiahossain):

ok, then

OpenStudy (kayders1997):

Now what?

OpenStudy (nadiahossain):

divide?

OpenStudy (kayders1997):

Yes

OpenStudy (nadiahossain):

but how?

OpenStudy (kayders1997):

Because you have your 340,000/2

OpenStudy (nadiahossain):

what about 5.6?

OpenStudy (nadiahossain):

where does that go?

OpenStudy (kayders1997):

Didn't we do that part already? Because subtraction is the last step we can't do it till we get the multiplaction and division done

OpenStudy (nadiahossain):

oh ok

OpenStudy (kayders1997):

So your division would be?

OpenStudy (nadiahossain):

170?

OpenStudy (kayders1997):

170,000 dont forget the extra zeros and now you have to?

OpenStudy (nadiahossain):

I got 170 only by dividing it

OpenStudy (kayders1997):

340,000/2?

OpenStudy (nadiahossain):

you mean 2,000

OpenStudy (kayders1997):

What?

OpenStudy (kayders1997):

Right now we have 5,600,000-340,000/2×1000

OpenStudy (nadiahossain):

oh ok

OpenStudy (kayders1997):

Do you understand why?

OpenStudy (nadiahossain):

noo

OpenStudy (kayders1997):

Okay so you understand the parenthesis right?

OpenStudy (nadiahossain):

yeah

OpenStudy (kayders1997):

Good so we got done with the P for peMDAS next step any exponents? Yes 10^3=1000 understand?

OpenStudy (nadiahossain):

yep

OpenStudy (nadiahossain):

then?

OpenStudy (kayders1997):

Okay so we have 5,600,000-340,000/2×1000 now we have to do the multiplaction and division from left to right

OpenStudy (nadiahossain):

ok

OpenStudy (kayders1997):

Does this make sense why you cant do 2×1000 than?

OpenStudy (nadiahossain):

yep

OpenStudy (kayders1997):

So you have to do the division first so you get?

OpenStudy (nadiahossain):

170,000

OpenStudy (kayders1997):

Yes now you have to?

OpenStudy (nadiahossain):

multiply??

OpenStudy (kayders1997):

Yes!

OpenStudy (kayders1997):

So you will get?

OpenStudy (nadiahossain):

2,000?

OpenStudy (kayders1997):

Hmmmm?

OpenStudy (kayders1997):

What did you multiply together?

OpenStudy (nadiahossain):

2*1000

OpenStudy (kayders1997):

We got rid of the 2

OpenStudy (nadiahossain):

Can you draw like the problems with steps

OpenStudy (kayders1997):

When we divided

OpenStudy (kayders1997):

Sure can hyou just wait a second gotta get on computer

OpenStudy (nadiahossain):

ok

OpenStudy (nadiahossain):

Thank you so much for the help

OpenStudy (kayders1997):

nO problem :)

OpenStudy (nadiahossain):

:)

OpenStudy (kayders1997):
