Instruction Manual for Scientific Calculator

Absolute value: Abs and | |
           For each absolute value expression, make sure that a matching pair of vertical bars is used.
           When vertical bars are used to denote absolute value, this calculator is not designed to handle
           the case of absolute value expression nested inside another absolute value expression because it's too
           ambiguous to interpret user's intention. For an expression like | 2 + |-6 + 3| - 9 |, use "Abs".
           | 2 + |-6 + 3| - 9 | can be input as Abs(2 + Abs(-6 + 3) - 9).
