The argument of a complex number is angle of the line between the origin and the number measured with respect the positive real number axis.

In this case, we see directly that −10 has the argument .

NOTE: All angles that correspond to the same direction differ by a whole number of turns, i.e. a multiple of 2, and therefore we could have just as well answered −, 3, 5 etc. However, it is usual to give the argument between 0 and 2 or between − and .
