Lesson 9-δ: Absolute Values

レッスン 9-δ: 絶対値

The absolute value (| x |) of a real number x is the non-negative value of x without regard to its sign. For example, the absolute value of 5 is 5, and the absolute value of −5 is also 5. The absolute value of a number may be thought of as its distance from zero along real number line.

実数 x の絶対値 (| x |) は、符号に関係なく x の非負の値です。たとえば、5 の絶対値は 5 であり、-5 の絶対値も 5 です。数値の絶対値は、実数直線に沿ったゼロからの距離と考えることができます。
