Is it a number? Finally, since 7 can be written as a fraction with a denominator of 1, 7/1, then it is also a rational number. one objectit stands for negative three, the name of the number that is Let $ \mathbf{Q}$ represents the set of rational numbers. When we have a complex number of the form \(z = a + bi\), the number \(a\) is called the real part of the complex number \(z\) and the number \(b\) is called the imaginary part of \(z\). or sometimes the counting numbers. Any number that represents an We call the set of natural numbers plus the number zero the wholenumbers.
