This is the approximate square root of 5. , It cannot be both. The sets of rational and irrational numbers together make up the set of real numbers. As we saw with integers, the real numbers can be divided into three subsets: negative real numbers, zero, and positive real numbers. Each subset includes fractions, decimals, and irrational numbers according to their algebraic sign (+ or –)., Natural numbers are a set of positive numbers from 1 to ∞. Which is represented by ℕ symbol. And there is no default command in latex to denote natural numbers symbol. You will need to use an external package for this natural numbers symbol. Latex has four packages and each package has the same command to denote …, The treatment of negative real numbers is according to the general rules of arithmetic and their denotation is simply prefixing the corresponding positive numeral by a minus sign, e.g. −123.456. Most real numbers can only be approximated by decimal numerals, in which a decimal point is placed to the right of the digit with place value 1. Each ..., • A real number a is said to be nonnegative if a ≥ 0. • A real number a is said to be nonpositive if a ≤ 0. • If a and b are two distinct real numbers, a real number c is said to be between a and bif either a < c < b or a > c > b. • For any real number a, the absolute value of a, denoted by |a|, is defined by |a| = (a if a ≥ 0,
