Now let's write the exercise in the appropriate form:
We'll locate the number 6 on the number line and from there we'll move 11 steps to the left:
The answer is minus 5.
a is negative number.
b is negative number.
What is the sum of a+b?
The parentheses around (+6) and (+11) just show that these are positive numbers clearly. They don't change the operation - you still subtract normally!

Yes! is the same as . The parentheses just emphasize that the numbers are positive.
That would give you +5, which is incorrect! The order matters in subtraction. Always subtract the second number from the first: 6 - 11, not 11 - 6.
