Is every real number a complex number?give an example 1 See answer abus9994 is waiting for your help. Because a complex number is a binomial — a numerical expression with two terms — arithmetic is generally done in the same way as any binomial, by combining the like terms and simplifying. Here, the imaginary part of complex number is equal to 0 but it is still a complex number. Note that 0=0+0i, therefore 0 is both a real number and a pure Real numbers are simply the combination of rational and irrational numbers, in the number system.

So, is it mathematically (strictly speaking!) In the special case where b=0, a+0i=a. This way, a complex number is defined as a polynomial with real coefficients in the single indeterminate i, for which the relation i 2 + 1 = 0 is imposed. One can represent complex numbers as an ordered pair of real numbers (a,b), so that real numbers are complex numbers whose second members b are zero. A complex number is a+bi where a and b are real numbers and Step 2. Science Advisor.
