9

Step-by-step explanation:

the other answer is right.

to add a little bit of explanation :

you need to calculate the difference between -6 and +3.

and we are looking on the number line only for a distance and not for a direction, as the distance (or simple difference) between -6 and +3 is the same as between +3 and -6.

so, whatever we get as difference, we need to treat that result as positive number.

so, we get the difference between two numbers by subtracting one from the other.

either 3 - (-6), or -6 - 3

you do know that subtracting a negative number is the same as adding the same positive number ?

e.g. 3 - (-6) = 3 + 6 = 9

as for the other direction -6 - 3 = -9

but again, we have to take this in this context as a positive number.

in math we call this the absolute value of a number.

so, the answer is always 9.
