Introduction to Arithmetic:
Arithmetic is the most elementary branch of mathematics, used by almost everyone, for tasks ranging from simple day-to-day counting to advanced science and business calculations. It involves the study of quantity, especially as the result of combining numbers. In common usage, it refers to the simpler properties when using the traditional operations of addition, subtraction, multiplication and division with smaller values of numbers.

Example Arithmetic Problems:
Addition:
Arithmetic Problem example 1: In a vegetable basket 18 tomatoes and 17 potatoes. How many total vegetables are there in the vegetable basket?
Solution:
No. of tomatoes in the basket = 18
Number of potatoes in the basket = 17
Total vegetables in the basket = 18 + 17
Total vegetables in the basket = 35 fruits.
Subtraction:
Arithmetic Problem example 2: There are 67 seats in a compartment. 61 seats were occupied by the passenger. How many seats were not occupied?
Solution:
Total no. of seats in the class = 67
No. of seats occupied by the passengers = 61
No. of seats not occupied = 67 – 61
No. of seats not occupied = 6 seats.
Multiplication:
Arithmetic Problem example 3: A notebook cost 2 dollars. What is the price of 12 notebooks?
Solution:
Price of 1 notebook = 2 dollars
Price of 12 notebooks = 12 x 2
Price of 12 notebooks = 24 dollars.
Division:
Arithmetic Problem example 4: 5 trousers price is 25 dollars. What is the price of 1 trouser?
Solution:
Price of 5 trousers = 25 dollars
Price of 1 trouser = 25 / 5
Price of 1 trouser = 5 dollars.
