Answer:0Step-by-step explanation:3 - (-1) + (-1) -3 =Minus and a negative makes it positive. In other words it would be written like this: 3 + 1 + (-1) - 3 =Next step would be making it minus 1, because plus sign and negative makes the number to be subtracted. It would be rewritten like this: 3 + 1 - 1 - 3 = Then you will simply add 3 and 1, which makes it 4. So it would be rewritten likes this: 4 - 1 - 3 =Then you will simply subtract 1 from 4, which would equal to 3. So it would be rewritten like this: 3 - 3 =Last step, would be subtracting 3 from 3. Whatever is subtracted from itself would always be 0. So the answer would be 0!
