The direct use of the infinity symbol in mathematics arises in order to compare the sizes of the sets such as …A complex number is a combination of real values and imaginary values. It is denoted by z = a + ib, where a, b are real numbers and i is an imaginary number. i = √−1 − 1 and no real value satisfies the equation i 2 = -1, therefore, I is called the imaginary number.A natural number can be used to express the size of a finite set; more precisely, a cardinal number is a measure for the size of a set, which is even suitable for infinite sets. This concept of "size" relies on maps between sets, such that two sets have the same size, exactly if there exists a bijection between them.You know what the equal symbol means and looks like. If a = b, then a and b are equal, (8 = 8). To learn about ordering real numbers, think about it this way. If a real number b is greater than a real number a, their relationship would look like this: −2 > −5 since −2 is to the right of −5 on the number line.
