To find which symbol to use to compare the expressions, add or subtract on each side. 922 811 7 9 Sometimes you will need to find an unknown number. For an equation, there will be one correct answer. For an inequality, there will be a set of numbers. 31 58 31 31558 Any number greater than 5 makes the inequality true. Compare.
