Operations on Numbers
Operations on Numbers are the most fundaments building block of mathematics and are used to manipulate numerical values. These operations are as follows:
Division
In Division, we can divide a number into equal parts. For example, 12 ÷ 3 = 4 means 12 can be shared into 3 equal parts, each part is 4. The image added below shows the division between 21 ÷ 7 =3.
Multiplication
Multiplication is used when we need to add a number a certain number of times, so instead of repeatedly adding it, we just multiply it by the number of times it needs to be added. For example, 3 x 4 = 12 means 3 + 3 + 3 + 3 = 12. The image added below shows the multiplication between 21 × 3 = 63.
Addition
The addition is the most basic operation which combines two or more numbers to get a sum. For example, 2 + 3 = 5, 3+1/2=7/2, 2.14 + 3.73 = 5.87, etc. The image added below shows the addition between 21 + 3 = 24.
Subtraction
Subtraction is used for finding the difference between two numbers. For example, 6 – 4 = 2, 3-1.5 = 1.5, 3/2-1/3 = 7/3, etc. The image added below shows the addition between 21 – 3 = 18.
What are Numbers?
Numbers in math are the most fundamental thing invented by mankind to serve its vast variety of endeavors in science and technology. From sending rockets to Mars to calculating bills for groceries, numbers are used everywhere. Nowadays, we can’t think of mathematics without Understanding numbers.
There are different types of numbers like natural numbers, integers, rational numbers, irrational numbers, real numbers, complex numbers, prime numbers, composite numbers, algebraic numbers, transcendental numbers, even and odd numbers, and many, many more.
In this article, we will discuss what are numbers with examples, definition, types, history, operations on numbers, and practice problems.
