Learn how to think about absolute value as distance from zero, and practice finding absolute values. The absolute value of a number is its distance from 0 . This seems kind of obvious. Of course the distance from 0 to 4 is 4 . Where absolute value gets interesting is with negative numbers. Likewise, any integer can be expressed as the ratio of two integers, thus all integers are rational. However, numbers like √2 are irrational because it is impossible to express √2 as a ratio of …A point on the real number line that is associated with a coordinate is called its graph. To construct a number line, draw a horizontal line with arrows on both ends to indicate that it continues without bound. Next, choose any point to represent the number zero; this point is called the origin. Figure 1.1.2 1.1. 2.Radicals - The symbol $$\sqrt[n]{x}$$ used to indicate a root is called a radical and is therefore read "x radical n," or "the nth root of x." In the radical symbol, the horizontal line is called the vinculum, the quantity under the vinculum is called the radicand, and the quantity n written to the left is called the index.Now, some references. Dedekind used the letter R (uppercase) for the set of rational numbers in Stetigkeit und irrationale Zahlen (1872), $\S 3$, page 16 ("die Gerade L ist unendlich viel reicher an Punkt-Individuen, als das Gebiet R der rationalen Zahlen an Zahl-Individuen", i.e. "the straight line L is infinitely richer in point-individuals than the domain R of rational numbers in number ...

The set of rational numbers, written ℚ, is the set of all quotients of integers. Therefore, ℚ contains all elements of the form 𝑎 𝑏 where 𝑎 and 𝑏 are integers and 𝑏 is nonzero. In set builder notation, we have ℚ = 𝑎 𝑏 ∶ 𝑎, 𝑏 ∈ ℤ 𝑏 ≠ 0 . a n d.Inequality symbols. Inequality symbols are symbols that are used to indicate inequality relations. Together with other mathematical symbols such as the equals sign (=), which indicates an equality relation, they are sometimes referred to as relation symbols. Strict inequalities include less than (<) and greater than (>) symbols, described below.To divide one rational expression by another, we write the two expressions out with the division symbol between them. Flip (or invert) the fraction on the right side of the division symbol, so that the numerator and denominator switch places. Change the division symbol to a multiplication symbol, and multiply the two expressions together.Usage.

Any fraction with non-zero denominators is a rational number. Some of the examples of rational numbers are 1/2, 1/5, 3/4, and so on. The number “0” is also a rational number, as we can represent it in many forms ... It is rational since 0 can be expressed as fractions such as 0/3, 0/16, and 0/45. 3) [latex]0.3\overline {18}[/latex] This number obviously doesn’t belong to the set of natural numbers, set of whole numbers, and set of integers. Observe that 18 is repeating, and so this is a rational number. In fact, we can write it as a ratio of two integers.Radical expression s are expression containing a radical symbol (root) of a radicand (a number or a polynomial). An index indicates the root value (3rd root, 5th root and so on). Radical expressions are used to express values in their exact form instead of an approximate form. Radicals are inverses of rational exponents.A rational number is a number that can be expressed as the quotient or fraction pq of two integers, a numerator p and a non-zero denominator q.
