In print, the vertical bar is usually shown below the sign of comparison. You may also see a horizontal bar used with a sign of comparison such as greater than or less than. ⠼⠢⠨⠦⠐⠂⠲⠲⠣⠱⠻ Less Than or Equal to and Greater Than or Equal to Finally use the termination indicator (dots one two four five six) after the last number that is covered by the horizontal bar. In this case it is the horizontal bar, dots one five six. The next symbol is the symbol you wish to place over the expression. ![]() For the purposes of these problems, since the bar indicating the repeating decimal is above the numbers, you would use the directly over indicator. Use either the directly over (dots one two six) or the directly under (dots one four six) indicator. Next, you should input the expression or digits that are covered by the bar. First, the multipurpose indicator, dot five, must be used directly before the first digit under the bar. If, however, there is more than one digit in the expression or if the bar is above more than one digit, then you must use the rules for modifying an expression. If the expression contains a single digit that repeats an infinite number of times, the digit is followed by the symbol for a horizontal bar, dots one five six. ![]() When used with decimals, the raised bar indicates that the digit or series of digits covered by the bar repeat an infinite number of times over and over. The bar, dots one five six, is often used to show the repeating portion of decimals to indicate a sample mean in statistics, or as a line segment in geometry. The use of a bar is one example where this occurs. Such is the case when a shape needs to be placed above or below another symbol. Lesson 6.2: The Horizontal Bar - Repeating Decimals, Greater than or equal to, and Less than or equal to SymbolsĪs discussed before, shapes may need to be modified for special purposes.
