Question from Fatma Al Naqar – Section C
Dear Mr. Kevin
1. I’m not sure about the answer of the Question in page 3 of the 2nd Quiz (Q4) it was about the flu is it … 8x+27y ???
Actually, I accepted two answers. I accepted 4x+9y (people started counting on Monday) and I also accepted 8x+27y (including Sunday). The text is not clear enough to accept only one answer.
2. for what Khadegah asked, I have the same Question but……..
If we have the property as multiplicative identity or additive identity or any property else than substitution .. do we have to write it as substitution too?? plus the real property for example 7. 0=0 the property then would be multiplicative property of 0. do we have to add substitution too ( mentioning that we have to do that for almost all the changes we do in each step).or just give the priority for what the expression really present?
Example:
6+7*0
=6+0 (multiplicative property of zero AND substitution)
=6 (additive identity AND substitution)
However, it is not such a big deal if you do not mention the substitution property since we focus more on the other properties. As you say, the substitution property is everywhere!
3. for the measurements, there are some obvious Questions that we can solve without hesitation, but there are others that I really can’t distinguish whether the answer is right or wrong. for example:
” the mass of a dollar bill would best measured in………”
I wrote gram but it was milligrams (after measuring it with the balance in class) and in another question ” A small paper clip has a mass of about 1………..”
I wrote milligrams but it was gram ( after measuring) so how can we guess the right answer for such questions?
Don’t worry about it. I agree with you that the mentioned questions are a little confusing. The questions in the exam will be clear, no room for doubt!
and.. thank you!!
An .. your welcome!

Question from Khadega – Section C
Dear Mr,Kevin,
How are you? If you don’t mind I want to ask you a simple question.
Is it necessary to write the property substitution in each step of the
solution?
My answer
Hi Khadega!
It is indeed recommended to specify when you use the substitution property.
Good Luck!
Kevin
