### sense in the lessons

Important in maths: «6 ÷ 0 is undefined», because no number times 0 gives 6. In computing lessons, «undefined» appears as an error when something has no value. In everyday talk: «an undefined role» means nobody said exactly what the job is.

### note

In maths, «undefined» is not the same as 0: 0 ÷ 6 = 0, but 6 ÷ 0 is undefined. «Define» means to give the exact meaning. Opposite: «defined».
