This is a question that is useless, but would someone kindly answer this for me? I tried to calculate this and it wouldn’t work. So if there is a way someone can, that would be very appreciated. Thank you

Calculate: -3.00 + -2.00 + -00.50 + 00.50 + -00.50 + -2.00 + -4.50 + -14.50 + -4.00 + -1.00 + 1.00 + -00.50 + -10.00
