How to write Latex real part symbol of a complex number? The real number a is called the real part of the complex number a + ib. Let $a,b\in \mathbb{R}$ and $z=a+ib \in \mathbb{C}$. Real part and imaginary part are defined like follows: \[\begin{array}{ccc} a & + & ...
All real numbers lie on the number line, so, they can be compared and ordered. If we can order real numbers, then we can add, subtract, multiply and divide real numbers. There are an infinite number of numbers in all of the given subsets. Natural and whole numbers can be enumerated us...
