take any negative number, and subtract a positive number..that is the same as adding a negative number and two negative numbers added together are a negative number.
If a positive and negative number are added together, and the positive number has a greater value, the sum will be positive.
Any positive number added to it's negative is always = 0
If "a" is multiplied or divided by a positive it will be negative.If "a" is added to a number less than 23 it will be negative.
