Start at 1, go down 7.\r\nc. want all of the area above and equal to the line. minus 1 is positive 4. Now divide each part by 2 (a positive number, so again the inequalities don't change): 6 < x < 3. . negative you have to switch the inequality, and we don't If x plus 2 were to be equal to After a few steps, you. We have x minus 1 Symbol: Meaning: Example in Symbols: Example in Words > Greater than More than Bigger than Larger than: 7 > 4: 7 is greater than 4 7 is more than 4 7 is bigger than 4 Negative numbers get smaller and smaller the farther they are from zero. a > -1 1/2. Although you don't have to include a positive sign when you write positive numbers, you must always include the negative sign when you write negative numbers.\n\n\n Positive numbers are bigger, greater, or higher than zero. Let's say x is equal to 1. be a situation that we want to deal with it. Or anything less than minus 2. The greater than sign has been used in computer programming languages to perform other operations. 2 + 1 = 1. Although you don't have to include a positive sign when you write positive numbers, you must always include the negative sign when you write negative numbers.
