Math Symbols, Signs And Explanation
- + (Addition)
- Use: Adds two numbers together.
- Example: 3+2=53 + 2 = 53+2=5
- – (Subtraction)
- Use: Subtracts one number from another.
- Example: 7−4=37 – 4 = 37−4=3
- × (Multiplication)
- Use: Multiplies two numbers together.
- Example: 5×3=155 × 3 = 155×3=15
- ÷ (Division)
- Use: Divides one number by another.
- Example: 10÷2=510 ÷ 2 = 510÷2=5
- = (Equals)
- Use: Shows that two values are the same.
- Example: 8=88 = 88=8
- < (Less Than)
- Use: Shows that one number is smaller than another.
- Example: 3<53 < 53<5
- > (Greater Than)
- Use: Shows that one number is larger than another.
- Example: 7>47 > 47>4
- ≤ (Less Than or Equal To)
- Use: Shows that one number is smaller than or equal to another.
- Example: 6≤66 ≤ 66≤6
- ≥ (Greater Than or Equal To)
- Use: Shows that one number is larger than or equal to another.
- Example: 9≥59 ≥ 59≥5
- ≠ (Not Equal)
- Use: Shows that two values are not the same.
- Example: 4≠74 ≠ 74=7
Math Symbols, Signs And Explanation
- % (Percent)
- Use: Represents a number as a fraction of 100.
- Example: 25%25\%25% means 252525 out of 100100100.
- √ (Square Root)
- Use: Represents a number which, when multiplied by itself, gives the original number.
- Example: √9=3√9 = 3√9=3 because 3×3=93 × 3 = 93×3=9
- ∆ (Change/Delta)
- Use: Represents a change or difference in a quantity.
- Example: ∆x∆x∆x indicates a change in the variable xxx.
- ∑ (Sum)
- Use: Represents the sum of a series of numbers.
- Example: ∑i=1ni∑_{i=1}^n i∑i=1ni represents the sum of numbers from 111 to nnn.
- π (Pi)
- Use: Represents the ratio of the circumference of a circle to its diameter, approximately 3.143.143.14.
- Example: In the formula for the area of a circle A=πr2A = πr^2A=πr2, πππ is used.
- ∞ (Infinity)
- Use: Represents a value that is unbounded or limitless.
- Example: ∞∞∞ can be used in contexts like limits in calculus.
- ( (Left Parenthesis)
- Use: Used to group numbers or variables in an expression.
- Example: (3+4)×2(3 + 4) × 2(3+4)×2
- ) (Right Parenthesis)
- Use: Used to close a group of numbers or variables.
- Example: (5−2)+6(5 – 2) + 6(5−2)+6
- { (Left Brace)
- Use: Used to group items, often in set notation or functions.
- Example: {1,2,3}\{1, 2, 3\}{1,2,3} denotes a set of numbers.
- } (Right Brace)
- Use: Used to close a group of items in set notation or functions.
- Example: {4,5,6}\{4, 5, 6\}{4,5,6}
- [ (Left Bracket)
- Use: Often used in intervals or matrices.
- Example: [1,5][1, 5][1,5] denotes an interval including 1 and 5.
- ] (Right Bracket)
- Use: Used to close intervals or matrices.
- Example: [2,6][2, 6][2,6]
