Addition and Subtraction of Integers
In this article, we will be discussing the topic of addition and subtraction worksheets. As we all know, math or mathematics is a subject that primarily deals with numbers. Also, arithmetic is an elementary branch of mathematics that includes addition, subtraction, division, and multiplication.
These operations of mathematics help in finding the sum or total or different of something. These operations can also help in comparing and dividing things equally. These operations apply to all real numbers. According to the addition and subtraction worksheets, integers fall under the category of real numbers.
If a student wants to become familiar with the topic of addition word problems, then he or she should learn about some basic rules of adding integers. To help students with that, we have attached an image below.
Readers can refer to this image to better solve addition word problems and learn more about how to solve mathematical problems that involve integers. It is recommended that students should also practice the addition of integers worksheet questions by referring to these rules.

Addition and Subtraction of Fractions
A fraction can be defined as a numerical part of a whole number. There are often math addition worksheets in which students have to solve questions related to fractions. This is why students should learn about different methods of adding or subtracting fractions.
Do you know what those methods are? If you don’t, then that is okay as we are going to mention all of those methods in this section. Go through the list that is given below to learn about those methods.
Adding or subtracting fractions with different denominators
Adding or subtracting fractions with same denominators
Adding or subtracting mixed number fractions
Let’s understand this topic by considering a math addition worksheets problem. Let’s assume that Malini ate one and a half rotis for lunch and two and a half rotis for dinner. Based on this information, calculate the total number of rotis that Malini ate.
In this example, it is important to add the fractions if one wants to arrive at the final answer. Here, we know that for lunch Malini had 1 + 1 / 2 roties while for dinner she had 2 and 1 / 2 roties. If one follows the method of adding fractions with the same denominator, then one can easily see that the total rotis Malini ate were 4.
Addition and Subtraction of Decimals
Now, let’s move on to discuss how one can solve addition and subtraction word problems that involve decimals. Understanding addition and subtraction related to decimals is a bit complex. But before we hop on to that discussion, let’s see what decimals mean.
The decimal number is used to represent a number that has greater precision in comparison to integers or whole numbers. These numbers are written with a dot within them. This dot is known as the decimal point. One can also consider decimals to be a simplified version of fractions.
This is why when it comes to the addition or subtraction of decimals, then one can employ the normal rules that are used for solving other addition and subtraction word problems. Let’s understand this with an example.
Let’s assume that two friends are contributing to buy a cricket ball together. We know that the total cost of the ball is INR 20. One of the friends has INR 7.50 while the other friend has INR 18.50. Now, let’s say that they both pooled their money and gave that money to the shopkeeper. Calculate the total change that the friends would receive in this problem that has been taken from the addition and subtraction worksheets pdf.
To solve this question, readers will first have to add the total amount of money that both the friends had. This means 7.50 + 18.50 = 26. We know that the cost of the ball was INR 20. So, now we need to subtract the cost of the ball from the total amount of money that the friends had. This means 26 - 20 = 6. Hence, the shopkeeper will return INR 6 to the friends.
Addition and Subtraction of Algebraic Expressions
According to the addition practice worksheets, an algebraic expression is a combination of constants, variables, and operators. Further, the addition practice worksheets state that four mathematical operations can be performed on algebraic equations. These mathematical operations are addition, subtraction, multiplication, and division.
Students often have to solve addition and subtraction worksheets pdf questions that involve algebraic expressions. And while solving those questions, students should remember that the addition and subtraction of algebraic expressions are similar to the addition and subtraction of real numbers.
The only difference lies in the fact that in the case of algebraic expressions, like and unlike terms, are sorted together. This is an important fact that students should remember while solving questions in addition to subtraction worksheets.
But what exactly is like and unlike terms? The answer to this addition worksheets questions is simple. Like terms are the ones that have the same variables and exponents. On the other hand, unlike terms are the terms that have different variables.
Let’s try to solve an addition worksheets question to understand this topic in a better manner. Find out like terms from the given equation: -5x2 + 12 xy - 3y + 7x2 + xy. In this equation, the like terms are -5x2 and 7x2 and the other pair of like terms is 12 xy and xy.
Fun Facts about Addition and Subtraction
Did you know that you can do almost all major equations with the help of four basic mathematical operations? These mathematical operations are addition, subtraction, division, and multiplication.
These operations can be used to solve both simple addition worksheets questions and real-world problems! We have also attached an image below that showcases all the four basic mathematical operations.
