Math is based on numbers, symbols, and formulas. Symbols, signs, or characters are used to represent numbers, operations, relationships between two or more values, and more. These symbols help us solve problems quickly. Let us learn more about them in this article.
Symbols save us from writing long and complicated equations, which in turn saves a lot of time and space. The symbols mentioned below are used in algebra.
Math Symbols Used for Constants
Constants are values that don’t change. In the table below, some of the math symbols used for constants are given along with their values and description.
Math Symbols Used in Logic
The following table shows the math symbols used in logic
Numeric Symbols
In the following table, you’ll find a collection of numeric symbols with examples of their use. Their Hindu-Arabic equivalents are also mentioned accordingly:
Math Symbols Used in Geometry
Symbols play an important role in geometry. In the following table, the commonly used geometrical symbols are listed, along with their names and examples:
Math Symbols Used in Venn Diagrams and Set Theory
The table below shows the mathematical symbols commonly used while working with Venn diagrams and set theory. They often denote the relationship between two or more sets.
Math Symbols used in Combinatorial
Combinatorics deals with counting and arranging objects. In the table given below, the symbols that are used to solve combinatorics problems are mentioned:
Symbols for the Greek Alphabets
Greek alphabets are often used as mathematical symbols. Below is a table with Greek letters along with their names and illustrative examples:
Math symbols are used widely in various fields like physics, engineering, and so on. Some of the key applications are mentioned below:
While working with math symbols, students tend to make mistakes. Take a look at some common mistakes given below to avoid them:
A square has an area of 25 cm2. What is the side length?
5cm
We can find the side of a square by using the formula:
Area = side2
So, side = 25 = 5
This concludes that each side of the square is 5cm.
Which is greater, 0.75 or 0.7?
0.75 is greater.
When 0.75 and 0.7 are compared, we know, 0.75 is greater than 0.7, so
0.75>0.7
So, 0.75 is greater.
A $400 jacket is 14% off. What is the sale price?
$344.
14% of 400 = 14100 400 = 56
Subtracting the discount from the original price, we get:
Sale price = 400 − 56 = 344
Find the circumference of a circle with radius 5 cm.
The circumference is approximately 31.5 cm.
Circumference formula:
C = 2r
C = 2 5 = 10 31.415cm
The circumference is approximately 31.5 cm.
You buy a pen for $1 and a book for $2.5. How do you pay in total to the shopkeeper?
You pay $3.50.
Pen = $1 and Book = $2.5
1 + 2.5 = 3.5
So, the total is 3.50.
