Tutor: Hi! I am now working on your question and you will soon see me writing on your drawing board.
Tutor: What is the value of 2(-3)
Student: -5
Tutor: No it is -6
Tutor: Here we are multiplying 2 with -3
Student: Oh multiply
Tutor: The brackets imply multiplication
Student: Ok
Tutor: yeah :)
Tutor: Any questions so far?
Student: No
Tutor: Here there are some rules which i want you to remember
Tutor: +(-) = -
Tutor: -(+) = -
Tutor: -(-) = +
Tutor: +(+) = +
Tutor: What this means is, if we are having a plus sign followed by minus sign, the sign fr the computation will remain as minus
Student: Ok copied it down
Tutor: Any questions so far?
Student: So that was subtract
Tutor: yes
Student: Ok
Tutor: Because we had one plus followed by one minus
Tutor: So subtract
Tutor: here since both signs are minus, you add the two numbers and place a minus sign in the beginning
Student: Thats wrong its -19-77
Tutor: oops
Tutor: thanks
Student: -96
Tutor: yes :)
Tutor: Any questions so far?
Student: No im catching on
Tutor: Here also 12/4 is 3
Tutor: And since there is only one minus sign , answer becomes -3
Tutor: But had it been ...
Student: Yes because 4 divided by 12 is 3
Tutor: -12/ -4 answer would have become +3
Tutor: Okay?
Student: Ok
Tutor: that is absolute value function or modulus function
Tutor: thus anything given within that number should be compared to positive
Tutor: Thus -224 become 224
Student: Ok so only thing you chnage is the sign
Tutor: *ocnverted
Tutor: Any questions so far?
Student: One sec
Student: Ok no
Student: So it became +224
Tutor: the answer is -224
Tutor: the green portion became 224
Student: Oh i thought it converted
Student: Ok
Tutor: let us first find lcm over here
Tutor: Any questions so far?
Student: So we have to find the lcd before doin the problem
Tutor: yes we have to
Student: Ok
Tutor: Not lcd, lcm..
Student: Ok least common multiple
Tutor: yes
Tutor: What is the value of 5-9-6
Student: 20
Tutor: no..
Student: +20
Tutor: Lets break that into two steps
Student: Oh ok
Tutor: In 5-9 we have to find 9-5 and put a negative sign at the front
Tutor: And -4 -6 is nothing but 4+6 with a negative sign in the front
Tutor: which grade are you in phyllis?
Student: In college math but math is a subject that i can not get with it just dont click with me i get so confused on everthing
Tutor: okay... you just need to practise and get familiar with the subject :)
Tutor: Any questions so far?
Student: No
Tutor: have you heard about the bodmas rule
Student: No
Tutor: it stands for brackets, of, division, multiplication, addition, subtraction
Tutor: This is the order of precedence for the various operations..
Student: Oh ok i need to write this down
Tutor: Thus we should always do division before addition or subtraction
Tutor: Yes do write it down
Tutor: Any questions so far?
Student: No keeping track so i can remember this
Tutor: ok
Student: When you finish can you do problem 16
Tutor: i have finished this
Tutor: Sure ill do 16
Student: Ok thanks
Tutor: division by 0 is not possible.. the answer will be infinity
Student: Ok wasnt so sure
Tutor: ok
Student: Thanks you are a good tutor you take your time and is understandable
Tutor: Are there any more questions that I can help you with?
Tutor: you are welcome :) thanks
