Imagine the number line. Suppose on the left it starts -6, -5, -4, -3, -2, -1, 0, +1, +2, +3, etc.
Let's calculate 2 x (-3).
The expression -3 says starting at zero, go left 3 steps. The expression 2 x means do it twice.
Where do you finish? -6
If you see why you finish on the left side, you have your answer.
What about minus x minus. Let's calculate (-2) x (-3).
Again -3 says starting at zero go left 3 steps. The expression -2 x means, no, go the other way instead -- twice.
Where do you finish? +6. Minus x minus = plus.
