#-6#

Explanation:

Adding two positive numbers would be #(+3) +(+3)#

#(+3) +(+3) = +6#

In the same way we can add two negative numbers

#(-3)+(-3)#

=#-6#

Think of this as going 3 units to the left, down the number line, and the going another 3 further down the number line.
You will end up at #-6#
