Mixed Operations

In this chapter, the students will learn about mixed operations for class 2. They will learn about the term addition, subtraction and multiplication. Also, they will learn about the properties of addition, subtraction, subtraction, and multiplication.

In this learning concept, the students will learn:

• Use of addition for class 2
• Use of subtraction for class 2
• Use of multiplication for class 2

Each concept is explained to class 2 maths students using illustrations, examples, and mind maps. You can assess your learning by solving the two printable worksheets at the end of the pages’.
Download the worksheets and check the solutions for the concept of mix operation worksheet for class 2 provided in PDF format.

We have learned the following operations:

Addition for Class 2: To find a total or count the objects together we use addition

Subtraction for Class 2: To find a difference we use subtraction.

Multiplication for Class 2: To carry out repeated addition of the same number.

 

Properties of Operation

Let’s see some properties of Addition, Subtraction, and Multiplication related to 0 and 1.

1.Addition:

1. 1. When we add 1 to any number, we get the next number as a sum.
   2. When we add 0 to any number, we get the same number as the sum.

Examples:

1. 45 + 1 = 46
2. 87 + 0 = 87

 

2.Subtraction:

1. When we subtract 1 from any number, we get the difference as a number that just comes before that number.
2. When we subtract 0 from any number, we get the same number as a difference.

Examples:

1. 88 – 1 = 87
2. 99 – 0 = 99

 

3.Multiplication:

1. When we multiply any number by 1, we get the same number as a product.
2. When we multiply any number by 0, we get the 0 as a product.

Examples:

1. 56 × 1 = 56
2. 34 × 0 = 0

 

Fact Family Addition and Subtraction:

There are some examples in which we use more than one operation.

 

Mixed Operation Word Problems:

To solve any word problem, follow the steps-

Step 1: Find out which operation we have to do.

Step 2: Identify the numbers with which we have to do that operation.

Step 3: Find out the answer.

Let’s see that examples:

1. Rohan has 10 pencils. His mother gave him 34 more pencils. Out of total pencils, Rohan gave 12 pencils to Nisha. Now find out how many pencils Rohan has?

Answer:

Step 1: Find out which operation we have to do.

Here first we have to do addition and then subtraction.

Step 2: Identify the numbers with which we have to do that operation.

So, let’s do the addition.

Rohan has 44 pencils; in which he gave 12 pencils to Nisha.

Step 3: Find out the answer.

So, let’s do the subtraction.

Now Rohan has left 32 pencils.

In the above example, we have done addition and subtraction.

1. Neelu has 4 boxes. In each box, there are 2 balls and 3 dolls. How many toys she has in total?

Answer:

Step 1: Find out which operation we have to do.

In each box, there are 2 balls and 3 dolls. So, first we have to do an addition.

Step 2: Identify the numbers with which we have to do that operation.

Step 3: Find out the answer.

2 balls + 3 dolls = 5 toys in each box.

There are total of 4 boxes and each box has 5 toys.

So, let’s do multiplication.

5 toys × 4 boxes = 20 toys

So, Neelu has 20 toys in total.

In the above example, we have done addition and multiplication.

In this way, by using mixed operations we can solve examples easily.
