Simplify -2 - (-2)
- (-2) = +2 so -2 + 2 =..
there is a minus sign before the first 2
so 0 -2 + 2 = 0
it is like 2 - 2 = 0
But i thought since a - is by a - it turns positive?
yes.. that is why the second 2 became positive - (-2) = +2
this is what i got: -2-(-2) -2+2 4-2=2
tell me how you got to the last line
-2+2 is 2-2 backwards
oh, then whats the final answer?
you wrote : -2-(-2) -2+2 4-2=2 so i agree with : -2-(-2) -2+2 but why did you wrote 4-2=2
so -2 + 2 is like 2 - 2 which is 0
think of -2 + 2 as like starting from 0 going left two steps (-2) and then going right two steps (+2) you end up at 0 again.
Oh. OHHHH i see, thank you so much guys. You wanna help me with my next one?
-3 - [ -(-2)]
so what do you think ? show me your steps
i dont even know where to start.
so what is : -(-2) ?
wouldnt it stay 2
correct so : -3 - [ 2 ]
now what ?
yes a negative times a negative is a positive
I not sure:(
so would it be +2?
- [ 2 ] will become +2 ?
- [ 2 ] is like - [ + 2] does it equal 2 ?
so the rules are : - ( - a ) = a [minus times minus = plus] - ( +a) = -a [minus times plus = minus] + (-a) = -a [plus times minus = minus]
now tell me what is -  ?
yes, we can write it as -[+2] but what is it according to the rules
ok so it would read -3-[+2]
yes so what is the answer ?
-[+2] according to the rules (the second line) is -2
so you have -3-2
no, -3-2 = -5
-3-2= -3 + -2 = -5
Oh i see, sometimes i have trouble figuring out negatives
yw, keep on practicing :)
