Mathematics is an important subject in exams and it is very useful for us in our whole life because the common thing that we do in our day-to-day life requires the knowledge of elementary mathematics. in Mathematics Symbols are very important.
The knowledge of Mathematical Notations and mathematical Symbols are very much required for a student who wants to improve his knowledge of mathematics and who wants efficiency in solving math problems. Below I am writing some of the very basic symbols and will update it as per your suggestions. please write your views on my writing approach as well as on the usefulness of this article by examspace.
I have categorized these symbols by their function into tables to make their reading easier for you. You can find different symbols in subsequent sections that will be useful for your math expedition. Go ahead…
Basic Math Symbols
In basic Math Symbols, i have written about the basic symbols like addition, subtraction, multiplication, division less than, greater than, and others please read this in the following table.
| Symbols | Name of the Symbols |
|---|---|
| + | Addition |
| – | Subtraction |
| x | Multiplication |
| ÷ | Division |
| > | Greater than |
| < | Smaller than |
| ≤ | Less than equal to |
| ≥ | Greater than equal to |
| ± | Plus Minus |
| ≠ | Not Equal to |
| = | Equals to |
| ≈ | Approximately equal to |
| 3√a | Cube Root |
| √ | Square root |
| n√a | nth root |
| % | Percentage |
| √ | Square root |
| : | Ratio |
| :: | Proportion |
| . | Decimal Point |
| ∵ | Since |
| ∴ | Therefore |
| ^ ( caret) | And |
| ∨(reverse caret) | Or |
| () | Parenthesis / Small Bracket |
| { } | Middle Bracket |
| [ ] | Big Bracket |
| ∞ | Infinity |
| ∝ | Varies as |
Symbols from Geometry
In geometrical notation, I have written symbols for angles, triangles, circle, and others. read this table for these geometry symbols
| Notations/Symbol | Name of Symbol | Example |
|---|---|---|
| ∟ | right angle | α = 90° |
| ∠ | angle | ∠ ABC = 30° |
 | measured angle |  ABC = 30° |
 | spherical angle |  AOB = 30° |
 | ray | |
 | line | |
 | Arc | |
| ∥ | parallel | AB ∥ CD |
| Δ | triangle | |
| ≅ | congruent to | ∆ABC≅ ∆XYZ |
| ~ | similarity | ∆ABC~ ∆XYZ |
| rad | radians | 360° = 2π rad |
| deg | degree | 360° |
| grad | gradians / gons | 360° = 400 grad |
| g | gradians | |
| c | radians | 360° = 2π c |
| π | pi constant | |
| r | Radius of Circle | |
| d | Diameter of circle | denoted as d |
| Ο | Circle | |
| ▭ | Rectangle | l=l, w=w |
Symbols from Algebra
Friends in the last go through with this small collection of symbols and notation collected from algebra.
| Symbol | Name of the Symbol | Example |
|---|---|---|
| x | x variable | unknown value to find |
| ⌊x⌋ | floor brackets | rounds number to lower integer |
| ⌈x⌉ | ceiling brackets | rounds number to upper integer |
| x! | exclamation mark | used to represent factorial |
| | x | | vertical bars | used to denote absolute value |
| f (x) | function of x | maps values of x to f(x) |
| [a,b] | closed interval | [a,b] = {x | a ≤ x ≤ b} |
| ∆ | delta | express the change / difference |
| ∆ | discriminant | Δ = b2 – 4ac |
| ∑ | sigma | summation – sum of all values in range of its series |
| ∑∑ | sigma | double summation |
| ∏ | capital pi | product – product of all values in range of series |
| ≡ | equivalence | identical to |
| ∝ | proportional to | proportional to/ tells about the variation |
| ≪ | much less than | much less than w.r.t some number |
| ≫ | much greater than | much greater than w.r.t some number |
| π | pi constant | usually pie = 3.141592654… pie is the ratio of circumference and diameter of a circle |
