Generally, the order in which we perform operations sequentially from left to right is: division, multiplication, addition, subtraction.

This order is expressed in short as ‘DMAS’ where ‘D’ stands for division, ‘M’ stands for multiplication, ‘A’ stands for addition and, ‘S’ for subtraction.

We first need to perform operation of the divisions and multiplications starting from the left towards the right and then perform operation of the additions and subtractions from the left to right.

-->Addition: Addition means combining parts to get a whole.

Example: Meena has 5 chocolates in her purse. Her mom gave her 7 more chocolates. How many chocolates does she have in total?Total Chocolates in Meena’s Purse = 5 chocolates + 7 Chocolates = 12 Chocolates.

Subtraction: Subtraction is the study of arithmetic operation for finding the difference between the two quantities or numbers.

Example:1) 6 - 6 = 0The value 6 minus value 6 equal to 0The solution is 0(zero).2) 12 – 24 = - 12The value 12 minus value 24 equal to minus 12The solution is minus 12

Multiplication: Multiplication is one type of arithmetic operations and repeated one number to the number of times equal to the other number. Symbol used for subtraction (x).

**Example: 229*101 means 101 times 229**

**= 100 times 229 + one time 229 ( by using multiplication method)**

**= 22900 + 229**

**= 23129**

**Division:**-->

**Division is one type of arithmetic operations and it is the process of repeated subtraction. Symbol used for division (÷).**

**Example:**Divide 40 by 8

**Solution:**40– 8 … (1)____32– 8 … (2)____24– 8 … (3)____16– 8 … (4)____8– 8 … (5)____0____So, 40 is divided by 8 in 5 times 40 ÷ 8 = 5
