Maya is showing her work in simplifying (5.2 − 4.5) − 5.5 + 4.8. Identify any error in her work or reasoning.
Welcome to QC, love the username BTW :P @Zowie
What are the steps she made? Is this the whole question? I need to whole question.
Step 1: (5.2 − 4.5) − 5.5 + 4.8 Step 2: 5.2 + (− 4.5 − 5.5) + 4.8 (identity property) Step 3: 5.2 − 10 + 4.8 Step 4: 5.2 + 4.8 − 10 (commutative property) Step 5: 10 − 10 = 0
which one is incorrect
Well you always have to use and follow PEMDAS. So it should look like this.
i may need to reset my acount
I
(5.2 − 4.5) − 5.5 + 4.8 You do what's in parenthesis first. (0.7)-5.5 + 4.8 Next is exponents. Well in this case there is no exponents. Same as multiplication and division. Next you would do addition. 0.7-10.3 Now the final step is subtraction. -9.6 That is what your answer should be. ^.^
Why is that? Can you not verify your email?
If you can't find the verification email, make sure to check spam!
Ok but where did she go wrong?
She went wrong in Step 2.
THANK YOU :)
Anytime! ^.^

Nope Mays original work was correct
?
-5.5 + 4.8 is not -10.3
I didn't say plus

not the numbers this part
(identity property)
(5.2 − 4.5) − 5.5 + 4.8 (0.7)-5.5 + 4.8 0.7-10.3 -9.6
part
That's what it should look like. If you are following the correct way to do math. PEMDAS.
*grabs popcorn*
me too
:)
When you
*passes popcorn to question*
(0.7)-5.5 + 4.8 0.7 - 5.5 + 4.8 = ?
guys not the number part
the (identity) part
When you add together 5.5 and 4.8 you get 10.3. Just because the number is positive it doesn't change the fact that there is a subtraction symbol after 0.7, so you will subtract 10.3 from 0.7
what should that part be
Go from left to right
Voca Google isn't always right. Google doesn't use PEMDAS. It just goes down the line. When doing math you have to use PEMDAS. No matter what. Question she still messed up on Step 2.
no
PEMDAS is the number one rule in math.
not the steps
I know what pemdas is Addition and subtraction have the same priority under pemdas
Look up "left to right rule"
Ok never mind I got it
chill everyone
Which of the following correctly uses absolute value to show the distance between −60 and 13? |−60 − 13| = |−73| = 73 units |−60 − 13| = |−73| = −73 units |−60 + 13| = |−47| = 47 units |−60 + 13| = |−47| = −47 units
can you answer this
Take the absolute value of the difference
-60 - 13 = ?
Still there?
yeah
I got a new name
I noticed
What is -60 - 13 = ?
-73
Good Now we take the absolute value So 73 is the distance
So A
TY
Which fraction is equivalent to 2 over negative 6?
Divide the numerator and denominator by 2

Woah, that was intense.
Indeed
Why do people interpret "Vocaloid is correcting someone's math" as "Vocaloid is angry?" They're just numbers, I'm not emotionally attached to them.
