Answer
$6$
Work Step by Step
We start with the given expression: $-6-(-12)$
First, we will convert this to an addition problem, using the rule $a-(-b)=a+b$: $-6+12$
We can find the sum of a positive and a negative integer by subtracting the smaller absolute value from the larger absolute value and giving the result the sign of the original number that has the larger absolute value.
Since $|12|>|-6|$, we can subtract $6$ from $12$, giving us $6$. Since the larger absolute value was originally positive, we give our result the positive sign: $6$
