Operation In Mathematics

Mixed operations are a set of operations in mathematics that can be defined as two or more operations, performed simultaneously on the same set of numbers. These are important to study in mathematics. Mixed operations are multiple operations involved like addition, subtraction, multiplication and division. Using PEMDAS or BODMAS rules, we demonstrate how to implement mixed operations. This article also helps you in attaining addition, subtraction, multiplication, and division worksheets pdf for free. So, let's begin.

What are Mixed Operations?

Mixed operations are those operations in which more than one operation is done. Suppose there is an expression, 5 + 2 -1. Here we can see that two operations are used. One is addition and the other one is subtraction. So such expressions will come under the mixed operations.

Order of Operation

The below-given image shows the order in which the operations are applied to a problem, having more than one operation.

Mixed Operations Rules

Following are the mixed operation rules:

Operation rule 1: First thing to do while operating the expression is to solve the numbers inside the parenthesis or bracket. We solve the parenthesis inside to out, grouping the operations. Observe the pattern of brackets present in the expression. There is an order to solve brackets, that is $[\{()\}]$. First, we solve the round bracket (), then the curly bracket {} then the box(square) bracket []. The order of operations to be followed inside the brackets.

Operation rule 2: After operating on parenthesis, we look for exponents. If present, solve them.

Operation rule 3: Now, we operate on the four basic operations. In this step, we look for numbers with multiplication and division operations. If present, solve them from left to right.

Operation rule 4: Last operations to be carried out are addition or subtraction and solving them from left to right.

Solved Mixed Addition and Subtraction Word Problems for Grade 2

Below are some addition and subtraction worksheets for grade 2:

Q 1. $4 \times(5+2)$

Ans: $4 \times(7)=28$ (Correct $(\checkmark)$.) This is a correct way to solve the parentheses) Let us look at another approach for the same expression. $4 \times(5+2)=20+2=22$ (Incorrect $(X)$.) This is an incorrect way to solve.

Q 2. $4 \times(-5)^2$

Ans: $4 \times(25)=100$ (Correct $(\checkmark)$.) This is a correct way to solve the exponents)

Another approach for the same expression may be as follows

$4 \times(-5)^2=-20^2=-400$ ((Incorrect $(X)$.) This is an incorrect way to solve the exponent

Q 3. $3+5 \times 2$

Ans: $3+5 \times 2=3+10=13$ (Correct $(\checkmark)$. Correct order.)

Another approach for the same expression may be as follows

$3+5 \times 2=8 \times 2=16$ (Incorrect $(X)$. Incorrect order.)

Practice Problems

Here are some practice problems based on the addition and subtraction worksheets;

Summary

Mixed operation is a mathematical concept that is used in many different fields of mathematics. It is used to describe situations where an operation produces more than one result, and can be viewed as a combination of two or more different operations. This concept can be applied to many fields such as combinatorics, probability and statistics. In this article, we tried to discuss some of these mixed operations in mathematics terms, along with some solved mixed addition and subtraction word problems for grade 2. If you understand the concept, you may find it interesting to solve the given addition and subtraction worksheets, even if you don't like studying mathematics.
