-3.5 + 85.95 = 82.45 But how do you get that answer, what do you do?

I don't understand

Do you need to change the sign -/+?

Or do you need to change the negative?

Also if you want to answer this.

What do you do when adding two negatives?

For example, -34.78 + (-29.45)

Please help, Thank you.
