Practice set 1: Finding absolute value. To find the absolute value of a complex number, we take the square root of the sum of the squares of the parts (this is a direct result of the Pythagorean theorem): | a + b i | = a 2 …The field of all rational and irrational numbers is called the real numbers, or simply the "reals," and denoted R. The set of real numbers is also called the continuum, denoted c. The set of reals is called Reals in the Wolfram Language, and a number x can be tested to see if it is a member of the reals using the command Element[x, Reals], and …

The unambiguous notations are: for the positive-real numbers R>0 ={x ∈ R ∣ x > 0}, R > 0 = { x ∈ R ∣ x > 0 }, and for the non-negative-real numbers R≥0 ={x ∈ R ∣ x ≥ 0}. R ≥ 0 …Example 3: Express the set which includes all the positive real numbers using interval notation. Solution: The set of positive real numbers would start from the number that is greater than 0 (But we are not sure what exactly that number is. Also, there are an infinite number of positive real numbers. Hence, we can write it as the interval (0, ∞).The set obtained by adjoining two improper elements to the set of real numbers is normally called the set of (affinely) extended real numbers. Although the notation for this set is not completely standardized, is commonly used. The set may also be written in interval notation as .With an appropriate topology, is the two-point …The Scientific format displays a number in exponential notation, replacing part of the number with E+n, in which E (exponent) multiplies the preceding number by 10 to the nth power. For example, a 2-decimal scientific format displays 12345678901 as 1.23E+10, which is 1.23 times 10 to the 10th power. A number format does not affect the actual cell …
