Question: `q003. If you are earning 8 dollars / hour, how long will it take you

to earn $72? The answer may well be

obvious, but explain as best you can how

you reasoned out your result.

YYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYY

Your solution: (type in your solution

starting in the next line)

72/8= 9

confidence = 3 OK

*********************************************

Question: `q004. Calculate (8 + 3) * 5

and 8 + 3 * 5, indicating the order of

your steps. Explain, as best you can, the

reasons for the difference in your

results.

YYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYY

Your solution: (type in your solution

starting in the next line)

(8 + 3) * 5 = 11 * 5 = 55

8 + 3 * 5 = 8 + 15 = 23

The difference comes from changing the

order you perform your operations because

of the parentheses

confidence = 3 OK

*********************************************

Question: `q005. Calculate (2^4) * 3

and 2^(4 * 3), indicating the order of

your steps. Explain, as best you can, the

reasons for the difference in your

results. Note that the symbol '^'

indicates raising to a power. For

example, 4^3 means 4 raised to the third

power, which is the same as 4 * 4 * 4 =

64.

YYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYY

Your solution:

(2^4) * 3 = 16 * 3 = 48

2^(4 * 3) = 2^12 = 4096

The difference comes from changing the

order you perform your operations because

of the parentheses

confidence = 3 OK

*********************************************

Question: `q006. Calculate 3 * 5 - 4 * 3

^ 2 and 3 * 5 - (4 * 3)^2 according to the

standard order of operations, indicating

the order of your steps. Explain, as best

you can, the reasons for the difference in

your results.

YYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYY

Your solution:

3 * 5 - 4 * 3 ^ 2= 15 - 4 * 9 = 15 - 36 =

-21

3 * 5 - (4 * 3)^2= 15 - 12^2 = 15 - 144 =

Question: `q007. Let y = 2 x + 3.

(Note: Liberal Arts Mathematics students

are encouraged to do this problem, but are

not required to do it).

Evaluate y for x = -2. What is your

result? In your solution explain the

steps you took to get this result.

Evaluate y for x values -1, 0, 1 and

(Note: Liberal Arts Mathematics students

are encouraged to do this problem, but are

not required to do it).

(Note: Liberal Arts Mathematics students

are encouraged to do this problem, but are

not required to do it).

Evaluate y for x = 1. What is your

result? In your solution explain the

steps you took to get this result.

Question: `q010. If you divide a certain

positive number by 1, is the result

greater than the original number, less

than the original number or equal to the

original number, or does the answer to

this question depend on the original

number?

Always equal

confidence = 3 OK

.............................................

Given Solution: If you divide any number

by 1, the result is the same as the

original number. Doesn't matter what the

original number is, if you divide it by 1,

you don't change it.

True

confidence = 3 OK

Question: `q011. If you divide a certain

positive number by a number greater than

1, is the result greater than the original

number, less than the original number or

equal to the original number, or does the

answer to this question depend on the

original number?

depends on the given number negative

numbers get bigger, positive numbers get

smaller

confidence = 3 OK

*********************************************

Question: `q013. Students often get the

basic answers to nearly all, or even all

these questions, correct. Your instructor

has however never seen anyone who

addressed all the subtleties in the given

solutions in their self-critiques, and it

is very common for a student to have given

no self-critiques. It is very likely that

there is something in the given solutions

that is not expressed in your solution.

This doesn't mean that you did a bad job.

If you got most of the 'answers' right,

you did fine.

However, in order to better understand the

process, you are asked here to go back and

find something in one of the given

solutions that you did not address in your

solution, and insert a self-critique. You

should choose something that isn't trivial

to you--something you're not 100% sure you

understand.

If you can't find anything, you can

indicate this below, and the instructor

will point out something and request a

response (the instructor will select

something reasonable, but will then expect

a very good and complete response).

However it will probably be less work for

you if you find something yourself.

Your response should be inserted at the

appropriate place in this document, and

should be indicated by preceding it with

####.

As an answer to this question, include a

copy of whatever you inserted above, or an

indication that you can't find anything.

@& Instructions request that you insert your responses into a copy of the original web document. You appear to have eliminated some of the text from the original document.

The original text includes certain strings of characters that allow me to efficiently isolate your insertions from the rest of the text, allowing me to review much more student work, much more accurately, than would otherwise be possible.

These and other characters are also used as triggers in collecting databases of student responses, and in some instances the lack of these characters can cause your document not to post at all.

If so requested below, you should resubmit this document, and insert your responses into a complete, unaltered copy of the original document. If you are not specifically requested to do so on this document, it won't be necessary, but you should follow this practice on all future submissions.

It is also possible that you have submitted other documents in which you have removed information from the original, rather than inserting your responses into an unaltered copy of the document. If this is the case, you should resubmit those documents, with your responses copied into complete copies of the originals.
