- anonymous

there is a minus sign before the first 2

- anonymous

so 2

- anonymous

0

- anonymous

so 0
-2 + 2 = 0

- anonymous

it is like
2 - 2 = 0

- anonymous

But i thought since a - is by a - it turns positive?

- anonymous

yes..
that is why the second 2
became positive
- (-2) = +2

- anonymous

-2+2

- anonymous

this is what i got:
-2-(-2)
-2+2
4-2=2

- anonymous

tell me how you got to the last line

- anonymous

-2+2 is 2-2 backwards

- anonymous

oh, then whats the final answer?

- anonymous

2-2=0

- anonymous

-2+2=0

- anonymous

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

- anonymous

idk

- anonymous

so
-2 + 2
is like
2 - 2
which is 0

- anonymous

^^^^^ exactly

- anonymous

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.

- anonymous

Oh. OHHHH i see, thank you so much guys. You wanna help me with my next one?

- anonymous

ok

- anonymous

-3 - [ -(-2)]

- anonymous

so what do you think ? show me your steps

- anonymous

i dont even know where to start.

- anonymous

so what is : -(-2) ?

- anonymous

wouldnt it stay 2

- anonymous

correct
so :
-3 - [ 2 ]

- anonymous

now what ?

- anonymous

yes a negative times a negative is a positive

- anonymous

I not sure:(

- anonymous

try :)

- anonymous

so would it be +2?

- anonymous

- [ 2 ] will become +2 ?

- anonymous

- [ 2 ] is like - [ + 2] does it equal 2 ?

- anonymous

..... idk....

- anonymous

so the rules are :
- ( - a ) = a [minus times minus = plus]
- ( +a) = -a [minus times plus = minus]
+ (-a) = -a [plus times minus = minus]

- anonymous

now tell me what is
- [2] ?

- anonymous

-[+2]

- anonymous

?

- anonymous

yes, we can write it as -[+2] but what is it according to the rules

- anonymous

ok so it would read -3-[+2]

- anonymous

yes so what is the answer ?

- anonymous

1?

- anonymous

No?

- anonymous

no

- anonymous

-[+2]
according to the rules (the second line)
is -2

- anonymous

so you have
-3-2

- anonymous

-1

- anonymous

no,
-3-2 = -5

- anonymous

-3-2= -3 + -2 = -5

- anonymous

Oh i see, sometimes i have trouble figuring out negatives

- anonymous

thank you:)

- anonymous

yw, keep on practicing :)
