The first one is wrong, the second one is correct.
Might I suggest a number line for you? This will easily help you to learn how to add and subtract positive and negative numbers!
The site I've given you allows you to create your own number lines! For problems such as these, I suggest entering -10 and 10 to start. Then you can make them longer if needed!

The first one should equal 6 but the second one is correct.
The first equation is like saying -2+(-4). When two negatives are added together, you add the terms and keep the negative sign.
In the second equation, the minus and negative signs cancel each other out so you would add 3 and 1.

-2-4=-6 if you have negative 2 and take away four more, you are going to be left with a smaller number, not the same amount.
3--1=4 two negatives cancel each other out.

The second one is correct. Subtracting a negative is the same as adding the number.
The first one is incorrect. You have started out by moving 2 steps in the negative direction. You then move 4 more steps in the negative direction. That puts you at 6 steps in the negative direction. The correct answer is -6.
