Math Symbols, Signs And Explanation

 

  1. + (Addition)
    • Use: Adds two numbers together.
    • Example: 3+2=53 + 2 = 53+2=5
  2. – (Subtraction)
    • Use: Subtracts one number from another.
    • Example: 7−4=37 – 4 = 37−4=3
  3. × (Multiplication)
    • Use: Multiplies two numbers together.
    • Example: 5×3=155 × 3 = 155×3=15
  4. ÷ (Division)
    • Use: Divides one number by another.
    • Example: 10÷2=510 ÷ 2 = 510÷2=5
  5. = (Equals)
    • Use: Shows that two values are the same.
    • Example: 8=88 = 88=8
  6. < (Less Than)
    • Use: Shows that one number is smaller than another.
    • Example: 3<53 < 53<5
  7. > (Greater Than)
    • Use: Shows that one number is larger than another.
    • Example: 7>47 > 47>4
  8. ≤ (Less Than or Equal To)

  2. √ (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
  3. ∆ (Change/Delta)
    • Use: Represents a change or difference in a quantity.
    • Example: ∆x∆x∆x indicates a change in the variable xxx.
  4. ∑ (Sum)
    • Use: Represents the sum of a series of numbers.
    • Example: ∑i=1ni∑_{i=1}^n i∑i=1n​i represents the sum of numbers from 111 to nnn.
  5. 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.
  6. ∞ (Infinity)
    • Use: Represents a value that is unbounded or limitless.
    • Example: ∞∞∞ can be used in contexts like limits in calculus.
  7. ( (Left Parenthesis)
    • Use: Used to group numbers or variables in an expression.
    • Example: (3+4)×2(3 + 4) × 2(3+4)×2
  8. ) (Right Parenthesis)
    • Use: Used to close a group of numbers or variables.
    • Example: (5−2)+6(5 – 2) + 6(5−2)+6
  9. { (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.
  10. } (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}
  11. [ (Left Bracket)
    • Use: Often used in intervals or matrices.
    • Example: [1,5][1, 5][1,5] denotes an interval including 1 and 5.
