Graph Paper Maker (free): Online Graphing Calculator(free): I. Model Problems The absolute value of a number is its distance from zero on the number line. For example the absolute value of 5, written |5|, is 5. Likewise, the absolute value of 5, written | 5| is also 5, because 5 is also 5 units away from zero on the number line. absolute value is always positive; if the absolute value of a variable equals a negative number, the solution to the equation is no solution. When solving absolute value equations , remember that there can be two solutions, because the absolute value of a number and its opposite are the same. Example 1 Solve |x| = 10.
If the absolute value of an expression equals a number, solve by setting up two equations, one with the expression equal to the number and the other with the expression equal to the opposite of the number.
