In a line with zero in the middle, negative numbers line up on the left, and positive numbers line up on the right: 4, 3, 2, 1, 0 1, 2, 3, 4.\nWhen you visualize negative and positive numbers in a line like this, it's easy to figure out which numbers are greater than others: For any two numbers in the line, the number to the right is always greater.\n\n \n Additive inverses are numbers that are opposite in sign but the same otherwise. Either both the numerator and from both sides. We already know that numbers farther to the right on the number line are greater for positive numbers. 6 (10) = 4. Let me get rid of that 1. But just think of 400 F and 12 F. Neither temperature is pleasant to think about, but 400 is definitely less pleasant colder, lower, smaller. out b is equal to negative 2. So ignore the signs and multiply or divide. Zero separates the positive numbers from the negative ones. or x is less than minus 2. If the test with 0,0 is true, then the shaded region includes the point 0,0, and if it's false, shade the opposite region which doesn't include the point 0,0. Cancel the adjacent minus signs to turn the problem into addition:\r\n17 (26) = 17 + 26 = 43\r\nb. Extend the idea of greater than and less than to negative numbers! Any other combination will result in a negative fraction (A/B<0 instead of A/B>0).
