Hence, the complex numbers are the combination of both the real number and imaginary numbers, CBSE Previous Year Question Paper for Class 10, CBSE Previous Year Question Paper for Class 12. Before we construct p-adic absolute values, we must understand what an absolute value is. Recall that the absolute value |x| of a real number x is itself, if it's positive or zero, but if x is negative, then its absolute value |x| is its negation -x, that is, the corresponding positive value.
