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.

Example
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
