Can you confirm if I did this assignment right because I am new to oline courses." "3. 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.
The question can be answered by 8 and dividing it into 72. This will give you 9. The answer is 9 hours. 3. Okay. Okay
4. 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.
A. (8+3) *5 can be solved by adding by 8 and 3 together, equaling 11. 11*5 equals 55. The answer is 55. B. 8+3*5 can be solved by multiplying 3 and 5 together. Giving you 15. 8+15 equals 23. The answer is 23. 3. Okay. Okay
5. 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.
A. 2 to the 4th power is just like saying 2*2*2*2 which is 16. 16 times 3 equals 48. The answer is 48. B. 3. Okay. Okay
6. 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.
A. For the first problem we will solve 3^2 first, giving us 9. Take the 9 and * it by 4, giving us 36. 3*5 will then be multiplied equaling 15. 15-36 is -21. The answer for this problem is -21. B. (4*3) will be done first because it is in parentheses, leaving us with 12. 12 will be taken and raised to the second power, which equals 144. 3*5 will be done next and that will be 15. We then will take 15-144 and our final result will be -129. 2. Okay. 2
10. 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?
Any positive integer divided by 1 will always stay the same. Ex: 4/1 =4. It is equal to the original. 3. Okay. Okay
11. Question: 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?
Any positive number that is divided more than one will always result in the number being smaller. The bigger the number is, the less that you will get. 3. Okay. Okay
12. Question: Question: `q012. If you divide a certain positive number by a positive number less 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?
Any positive number that is divided by less than one will result in a number that is greater than the original. Ex: is 4 is divided by 0.5 than the result will be 8. The less you divide by the greater the result will be. 3. Okay. Okay
13. 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.
In number 6 I did not explain the order of operation (PEMDAS). Someone might not know why the steps are in the order that I had them. ####

Very good.
Note, however, that you need to submit the entire document, without deleting anything.
