Why Are Math Symbols Important?

Math symbols simplify complex operations and reduce the need for lengthy explanations. Instead of writing "add three seven times," we simply write 3 x 7. 

Each symbol represents a specific operation or concept universally applied in all mathematical calculations and communication. 

A thorough knowledge of the meaning and applications of basic math symbol names helps students handle mathematical operations quickly and confidently.

Here's a list of some of the math symbols and names that we commonly use. Each math symbol with a name serves a particular purpose and helps express mathematical ideas efficiently.

Classification of Math Symbols

To make it easier to learn and remember, we can classify all math symbols and names into following categories: 

Arithmetic Symbols

These are the basic math symbols students frequently encounter while performing mathematical operations. The symbols are:

• + (addition)

• − (subtraction)

• × (multiplication)

• ÷ (division)

• / (fraction)

• . (Decimal)

Algebraic Symbols

These symbols express equations, formulas, and relationships between unknown values. These symbols include:

• = (equals)

• ≠ (not equals)

• <, >, ≤, ≥ (inequalities)

• x, y, z (variables)

• ^ (exponential)

• f(x) (function of x)

Geometric Symbols

These symbols help describe shapes, angles, and relationships. The geometry symbols in math are as follows:

• ∠ (angle)

• ° (degree)

• △ (triangle)

• ⊥ (perpendicular)

• ∥ (parallel)

• ≅ (congruence)

Set Theory Symbols

These math symbols are specifically used in set theory-related communication to describe groups of numbers or elements:

• {  } (collection of elements)

• ∈ (belongs to)

• ∉ (does not belong to)

• ⊂ (subset)

• ∪ (union)

• ∩ (intersection)

Math Symbols Solved Examples

The following examples show how different math symbols are used for problem solving in maths.

1. Add 3 times 18 and 5 times 12.

Solution:

3 times 18 = 3 x 18 = 54

5 times 12 = 5 x 12 = 60

Now, to add 54 and 60, we can write 54 + 60 = 114

So, the result is 114.

2. If a class has 9 girl students out of a total of 36 students, what is the percentage of girl students.

Solution:

Ans. The ratio of girl students to the total number of students is 9/36 = ¼

So, the percentage of girl students is = ¼ x 100 = 25% 

3. Find the perimeter of a circle with a radius of 14 cm.

Solution:

The formula for the perimeter of a circle is 2πr, where π is a constant and equals 22/7, and r is the circle's radius.

So, the perimeter of the given circle is:

(2 x 22/7 x 14) cm

= 88 cm

4. If f(x) = 4x + 14, find the value of f (9)

Solution:

Putting the value of x = 9 in the given equation, we get:

f (9) = 4 x 9 + 13 = 36 +14 = 50. 

5. Find the side of the square with an area of 64 square cm. 

Solution:

The side of a square is the square root of its area.

So, the side of the given square is square root of 64.

Now, √64 = 8

So, the side of the square equals 8 cm.
