Algebra Symbols
Covid-19 has led the world to go through a phenomenal transition .
E-learning is the future today.
Stay Home , Stay Safe and keep learning!!!
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
| For US students | For Indian students and UK students |

| P ---> Parenthesis { } E ---> Exponents M ----> Multiplication (x) D ---> Division (÷) A ---> Addition (+) S ---> Subtraction (-) |
B ---> Bracket { } O ---> Of (x) D ----> Division (÷) M ---> Multiplication (x) A ---> Addition (+) S ---> Subtraction (-) |
