Step-by-step explanation:

This is a list of commonly used symbols in the stream of mathematics.

Symbol Symbol Name Meaning or Definition Example

≠ not equal sign inequality 10 ≠ 6

= equals sign EQUALITY 3 = 1 + 2

< strict inequality less than 7 < 10

> strict inequality greater than 6 > 2

≤ inequality less than or equal to x ≤ y, means, y = x or y > x, but not vice-versa.

≥ inequality greater than or equal to a ≥ b, means, a = b or a > b, but vice-versa does not holds TRUE.

[ ] brackets calculate expression inside first [ 2×5] + 7 = 17

( ) parentheses calculate expression inside first 3 × (3 + 7) = 30

− minus sign subtraction 5 − 2 = 3

+ plus sign ADDITION 4 + 5 = 9

∓ minus – plus both minus and plus operations 1 ∓ 4 = -3 and 5

± plus – minus both plus and minus operations 5 ± 3 = 8 and 2

× times sign multiplication 4 × 3 = 12

* asterisk multiplication 2 * 3 = 6

÷ division sign / obelus division 15 ÷ 5 = 3

∙ multiplication dot multiplication 2 ∙ 3 = 6

– horizontal line division / FRACTION 8/2 = 4
