## Mathematical Symbols

Mathematical Symbols is a figure or a combination of figures that is used to represent a mathematical object, an action on mathematical objects, a relation between mathematical objects, or for structuring the other symbols that occur in a formula.
Here is the list of Mathematical Symbols:
1. Multiplication: (x) example 5x5 = 25, or you can use (*) 5*5 = 25.
2. Division: (/) or (÷) example 1/1=1, 1÷1=1.
3. Less than: (<) example 3<5.
4. greater than: (>) example 5>3.
5. Minus: (-) example 2-1=1.
6. plus: (+) example 2+2=4.
7. Equal symbol: (=).
8. Doesn't Equal symbol: (≠) example 5+1 ≠ 8.
9. Approximation symbol: (≈).
