Answer 1

If the question you're asking is -13-(-12), then your answer would be -1. Hope that helped.

Answer 2

Option C.

Explanation:

The given expression is

`-(1)/(3)-(-(1)/(2))`

We know that (-)(-)=(+). So, the given expression can be written as

`-(1)/(3)+(1)/(2)`

Taking LCM we get

`(-2+3)/(3* 2)`

`(1)/(6)`

The value of given expression is 1/6.

Two numbers are
`-(1)/(3)\text{ and }-(1)/(2)`. Mark these point on the given number number.

Now, move from
`-(1)/(2)` to
`-(1)/(3)` and count the number of jumps.

Number of jumps from
`-(1)/(2)` to
`-(1)/(3)` is 1.

1 Jump = 1/6

Therefore, the value of given expression is 1/6, therefore the correct option is C.
