In the question what is 11 plus negative 20 what is that answer

I promise you the answer is - 9. I wouldnt let you down man.

It would be - 9 because all u need to do is check to see which number is bigger the 11 or 20. So 20 is bigger and the - 20 ur going to take the negative sign and it's going to be in your answer so u know that the answer is a negative number. The 11 is positive and the 20 is negative so you start with 11 and count down 20 to get - 9
