What are Symbols in Math?
The symbols are special characters or figures that are used to represent different mathematical relations. There are different symbols in Math which are used in different conditions according to the requirement. The different types of symbols in Math include arithmetic symbols, logical symbols, calculus symbols and many more.
Some common symbols in mathematics are +, −, ×, ÷, =, <, >, ≤, ≥, √, ∑, ∏, π, Σ, Π, ∈, ∞, ±, ∠, °, %, ≈, ≠, and ∀.
