The Basics of Adding and Subtracting Integers
For math students, you may think that integers are ordinary numbers, but some people still confuse them with whole numbers. Before you learn everything about adding and subtracting integers, make sure that you know their exact definition. They resemble whole numbers, but the main difference is that integers contain zero and an additive inverse. It’s easy to conclude them whole numbers are just their subset or branch but without any decimals and fractions.
To master adding and subtracting integers successfully, get a clear understanding of the main types of numbers. Every number is different, but they all still share a set of common characteristics. You need to understand their basic differences and similarities, and this is when a special grouping system will come in handy because it’s used to describe and characterize each number based on its important characteristics.
Basically, the most common groups in this system include whole and natural numbers, rationals and integers, real numbers and others. When doing your homework that involves adding and subtracting integers, keep in mind that this system is quite similar to the main grouping concept in geography. This is where all things are grouped in specific categories according to the characteristics that are similar.
The Definition of Integers
What are integers? They describe a special category or group of numbers that are all negative or positive whole numbers (but they can’t include decimal or fractional parts) and consist of a set of numbers. When adding and subtracting integers, there are certain things that should be mentioned about them.
- They don’t have any decimals or fractions in any part.
- Zero belongs to integers.
- Negative numbers can represent the concept of being below standard values.
As a math student, you should understand that the categories of numbers tend to overlap similar to the groups of geography and make sure that notation won’t throw you off. For example, brackets are always used when writing sets because it’s a typical mathematical notation for listing a group of numbers. Besides, any ellipse while adding and subtracting integers means that number keep going on in the same pattern. This aspect is quite helpful when a group of numbers that must be represented is too big for writing it out in the entirety.
How to Add and Subtract Positive Integers
To get a better idea of adding and subtracting integers, you need to learn more about a number line and its definition. It turns basic mathematics into something physical and real because you can see it in front of you. The best part is that you can use them similar to calculators when performing this task, but you only need to use some common sense and several marks.
Start with drawing a simple number line and make a mark near its middle because it will be your zero. This mark is also called a point of origin, as this is where all numbers originate. The next step is drawing 2 marks, and each one should be placed on every side of 0. They will serve you as the integers that are closest to 0. You shouldn’t worry about making your spacing perfect at this stage of the process of adding and subtracting integers. That’s because your basic goal is to be close enough to determine the right meaning.
It’s necessary to complete a number line, and this task is easy to complete by adding more numbers. However, make sure that you have the right understanding of both negative and positive integers. The latter ones are considered natural numbers and include all integers that are larger than 0, while negative integers are always less than 0. Sometimes, people say that integers are used just as another way to name whole numbers. When it comes to fractions, they are only their parts, just like decimals, and this means that they can’t be integers.
It’s possible to use this simple number line to solve more complex problems with adding and subtracting integers or get prepared for other different areas in mathematics, including algebra. Take into account that all positive integers placed on its right side should be added, while the ones on the left side must be subtracted.
Tips on How to Add and Subtract Negative Integers
This process gets simple because you’re already familiar with a number line and its use. Besides, you also need to have a clearer idea of negative numbers. Positive numbers are movements to the right on this line, while the negative ones are movements to the left. This means that adding negative numbers moves pointers left on it. Take this simple tip into consideration when studying the basics of adding and subtracting integers.
You should use basic equations to understand the rules of adding negative numbers. Instead of performing this process, it’s necessary to turn such numbers into subtraction problems by using just positive numbers. You can go both ways: either by subtracting positive numbers or adding negative numbers. Don’t forget that you’re dealing with equations so that one part always equals another.
Find out more about adding and subtracting integers if they are negative, and how everything works on a number line. For instance, subtracting any negative number is the decrease in its length. You need to decrease the amount subtracted to see what will happen next, and you’ll end up with 1 less space to the left side of this line. Pay attention to how decreasing any decrease may result in increases. It’s required to change all minuses to pluses when adding any negative number and write its subtraction as addition.
Tips on Adding Large Positive Numbers
It’s another method involved in adding and subtracting integers, and it can help you learn more about dealing with large numbers. You should start with adding 2 numbers that are furthest to the right. This step may seem a bit odd, but you need to take it to end up with the right answer. Keep adding each number by using the same method and write all answers below every pair of given numbers. Your whole work should be checked to ensure that it’s free from accidental mistakes. Do the same thing with adding to finish math problems as normal. Keep moving to the left until the last number is added before trying any more complex problem. Every time you get a 2-digit number, you need to write only its last digit as your answer.
Finally, if adding and subtracting integers seems confusing or you don’t have enough time to master this subject because of other academic assignments, the good news is that you can use special services offered by freelancers. They are easily available over the Internet, and there are many students who keep benefiting from their use. You should look for their contact details online and get more information about offers and prices. You’ll be amazed to learn that the homework help services provided by freelancers are quite affordable so that your assignments can be done professionally without covering extra high expenses. Be sure to find a credible and experience specialist and use the works you order as future samples for your math homework.
