Algebra Symbols
In this section, we have given you algebra symbols, some rules to solve the expression. These rules are PEMDAS or BODMAS.The symbols are commonly used in word problems.Algebra is the branch of mathematics concerning the study of the rules of operations and relations, and the constructions and concepts arising from them, including terms, polynomials, equations and algebraic structures. Together with geometry, analysis, topology, combinatorics, and number theory, algebra is one of the main branches of pure mathematics.




1) x  x variable  Unknown Value to find.  3x = 6, then x = 2 
2) ≡  Equivalence  Identical to  3 ≡ 3 
3) ≈  Approximately Equal  Approximation  sin(0.02) ≈ (0.02) 
4) ∝  Proportional to.  Proportional to.  f(x) ∝ g(x) 
5) ∞  Lemniscate  Infinity Symbol.  
6) ≠  Not equal.  Inequality  5 ≠ 3 
7) ≤  Inequality  Less than or Equal to.  x + 5 ≤8 ⇒ x ≤ 3 
8) ≥  Inequality  Greater than or Equal to.  x  3 ≥ 10 ⇒ x ≥ 13 
9) ( )  parentheses  calculate expression inside first  2 ∗ (3+5) = 16 
10) [ ]  brackets  calculate expression inside first  [(1+2)∗(1+5)] = 18 
11) ⇒  Implies  Used to write a conclusion  2x=8 ⇒ x = 4 
12) ∴  Therefore  Used to write a conclusion  5x=5 ∴ x = 1 
The most important rule in solving Algebra is
