The primary difference is that subtraction is an operation that is performed as part of an expression. For example.... 2X - 4
Whereas a negative sign is not an operation but associated with an individual term in the expression..... 2X + (-4)
In the first example you are subtracting two positive "things" from each other. In the second example you are adding a positive "thing" and a negative "thing" together.
You will notice that if you were to substitute a number in for X in either of these expressions, or graph them as linear equations, you would obtain the same results for both.

What is 15 minus negative 22?
When dealing with addition and subtraction regarding negative numbers, it is important to remember that negative numbers will act in the opposite way as a positive number. For example, in this problem, 15 - (-22) , It may be easier to re-write it as this: 15 + 22 The negative sign of the 22 will be negated by the subtraction sign. 15 - (-22) = 37
