What is Arithmetic?
Arithmetic is the branch of mathematics that deals with the study of numbers using various operations on them. Basic operations of math are addition, subtraction, multiplication and division.
These operations are denoted by the given symbols.
The addition is the process of taking two or more numbers and adding them together. In other words, it is the total sum of all the numbers.
Addition of whole numbers results in a number greater than the added numbers.
Example: If 3 kids were playing and after some time, 2 more kids join them. How many kids are there in total?
This can be written as a mathematical expression as follows:
Subtraction is the process in which we remove objects from the original group.
In subtraction, the numerical value of the original number becomes less.
Example: 8 birds are sitting on a tree. After some time, 2 birds fly away. How many birds are on the tree?
Multiplication is adding the same number to itself a certain number of times.
When we multiply two numbers, the result is called a product.
Solution: Robin went to the garden 3 times. Every time he brought 5 oranges.
This can be mathematically written as 5 × 3 = 15 oranges
The division is breaking a large object or group into smaller parts or groups.
The number or the larger group that gets divided is known as the dividend.
The number that divides the dividend is known as the divisor.
The number obtained on dividing the dividend by a divisor is called the quotient.
The number left after dividing is called remainder.
Example: On distributing 26 strawberries among 6 children, each child gets 4 strawberries, and 2 strawberries are left.
