Then, if you're dealing with two numbers, the result is positive if the signs of both numbers are the same, and the result is negative if the signs of both numbers are different.\nCheck out the following examples:\n\nSo, 8 multiplied by 2 is 16, and because the signs of both numbers are different, the answer is negative, 16.\n\nSo, 5 multiplied by 11 is 55, and because the signs of both numbers are the same, the result is positive, +55.\n\nSo, 24 divided by 3 is 8, and because both numbers have different signs, the result is negative, 8.\n\nSo, 30 divided by 2 is 15, and because both numbers have the same signs, the answer is positive, +15.\nWhen multiplying and dividing more than two positive and negative numbers, use the Even-Odd Rule: Count the number of negative signs if you have an even number of negatives, the result is positive, but if you have an odd number of negatives, the result is negative.\nThe following examples show you how to use the Even-Odd Rule:\n\nThis problem has just one negative sign.

So the other way-- let is less than 0, we can just say that x has to be delta x would be positive 2 over negative 4, which 70 + 63 = 7. Thus, 3 is greater than 2, 2 > 1, 1 > 0, 0 > -1, -1 > -2 and so on . We already know that numbers farther to the right on the number line are greater for positive numbers. Additive inverses are always the same distance from zero (in opposite directions) on the number line.
