Teacher's Observation

Task 1 reviewIn task 1,you have to demonstrate both practical and algebric examples of any two types of variables and expressions along their explanations which were not discussed in class but you have only discussed and elaborated about qualitative and quantitative variables and their examples.I would like to ask that where are types of expressions? Average effort you made to answer this question!
Task 2 reviewIn task 2,when I read out starting paragraph of this task then I was impressed that you took a great start by properly explaining that PEMDAS rule will be applicable if you have to solve an algebric expression so you have taken a,2a and 1/2a as values of x,y,z which is your expression and then accordingly you put values and started solving and absolutely your solution is right but question is this haven't you seen that I have asked for step by step explanation for this task so if you have seen then you should understand that it needs to explain that how you are simplifying and evaluating this expression step by step which you haven't done so again an average effort you put for solving this task!
Task 3 reviewIn task 3,while doing simplification of 3(2x - 1) + 2(x + 4) - 5 expression you are right that according to PEMDAS rule you should solve parentheses first which you did accurately and then you directly jumped that (I did -3 ,-5).What was that?You need to tell step by step at least briefly what actually you are doing in your calculations!Again (x2 + 2x - 3) / (x + 1) when x = 2 in this expression you evaluated it correctly but your explanation is very general and not specific according to expression like it seems you are repeating PEMDAS rule in theoratical explanation of each expression solution.2x + 5 = 3(x - 2) + 1 in this expression similar things are repeating again and again by you like(I am solving parentheses,then exponents,then multiplication,then addition and at last subtractions) Average effort made by you in this task too!
Task 4 reviewIn task 4,if I talk about scenerio number 1 then you properly understood it and explained in a good way by sharing given data and then by calculating profit step by step and more you got final expression accurately for calculating total daily profit which is ${0.50ร—X+0.75ร—(X+30) but if I talk about scenerio number 2 then you misunderstood about simplification of total cost of car rented for x hours and you have only written equations for car rented for more than 4 hours and less than 4 hours.However,both of these equations should be simplified together for getting final outcome! Average effort made for attempting this task!

Recommendations:

I would like to recommend you to pay little more attention to details of each tasks as well as it would be important for you next time to read out carefully all points that are asked and don't be very hurry to solve it attempt tasks!
Hope you will learn with me!
Wish you good luck ๐Ÿ‘

Thank you, Professor, for your deep review. I should have give more attention my homework. I promise from the next lesson I will give more effort to my task.
