√x is a nonnegative number whose square is x. A⇒B means that if A is true, B must also be true, but if A is false, B is unknown. x=3⇒x 2 =9, but x 2 =9⇒x=3 is false, because x could also be -3. If A is true, B is true and if A is false, B is false. |x| is the distance along the real line (or across the complex plane) between x and zero.
The most basic symbols are the decimal digits (0, 1, 2, 3, 4, 5, 6, 7, 8, 9), and the letters of the Latin alphabet. The decimal digits are used for representing numbers through the Hindu–Arabic numeral system .
Symbols save time and space when writing. Here are the most common algebraic symbols:
In mathematics a rational number is a number that can be represented by a fraction of the form a b, where a and b are integers and b is not zero; the set of all rational numbers is commonly represented by the symbol Q or , which stands for quotient.

24 Σεπ 2024 · Symbols used in Algebra are illustrated below: x = 2, represents the value of x is 2. 1, 2, 3.... In x + 2, 2 is the numeral constant. If a ≠ b, a and b does not represent the same number. If a ≈ b, a and b are almost equal. If a ≜ b, a is definition of b. x ∝ y x = ky, where k is constant.
