∙ 15y agoThe three numbers are A, B and C We know that A + B + C = -4... and that A + B = -5
Therefore C = 1 B +1 = A (you say "decreased by" but I think that this is confusing, as I'll explain at the end.)
Therefore (B +1) + B = -5
Therefore 2B +1= -5
2B = -6
B = -3 A +(-3) +1 = -4
A - 3 = -5
A = -2 Now we have A = -2, B = -3, and C = 1
A + B = -2 + -3 = -5
A + B + C = -2 + -3 + 1 = -4 The confusion arises from saying that the second number is decreased, when the second number is obviously a negative value. The addition of a positive number to a negative one increases it.

What are two mathods of comparing numbers?
One option for comparing two numbers is to subtract the first number from the second number. If the result is less than zero, the first number is larger. If the result is greater than zero, the second number is larger. If the result is zero, the numbers are equal. Another option (for positive numbers) would be to divide the first number by the second number. If the result is greater than one, the first number is larger. If the result is less than one, the second number is larger. If the result is one, the numbers are equal. This rule flips if you are comparing negative numbers.
