Adding and Subtracting Negative Numbers
Adding and subtracting negative numbers can be tricky, but it’s important to understand how to do it correctly. After all, negative numbers are a part of everyday life! Here are some tips to help you master this math skill.
What are negative numbers?
Negative numbers are numbers that are less than zero. They are often used to represent debt or a decrease in value. When adding and subtracting negative numbers, it is important to keep track of the signs. A negative number added to a positive number will result in a smaller number, while a negative number added to another negative number will result in an even smaller number. For example, if you owe $10 and then borrow $5, you now owe $15. If you subtract a negative number from a positive number, the result will be a larger number. For example, if you have $10 and someone owes you $5, the total amount of money between the two of you is $15.
How to add and subtract negative numbers
Negative numbers are a bit more challenging to add and subtract than positive numbers, but understanding how to do so is critical for success in math. Here are some tips for adding and subtracting negative numbers:
When adding two negative numbers, the result is always a negative number. So, if you’re trying to add a positive number to a negative number, you would first add the two negative numbers together, and then subtract the result from the positive number. For example, if you’re trying to add -2 + 3, you would first add -2 + (-3) to get -5, and then subtract that from 3 to get -2.
When subtracting a negative number from a positive number, the result is always a positive number. So, if you’re trying to subtract a negative number from a positive number, you would first add the two numbers together and then take the result away from the positive number. For example, if you’re trying to subtract -2 from 3, you would first add -2 + 3 to get 1, and then take that away from 3 to get 2.
Examples of adding and subtracting negative numbers
When adding and subtracting negative numbers, it is important to remember that the signs of the numbers indicate whether they are positive or negative. Positive numbers are greater than zero, while negative numbers are less than zero. To add two positive numbers, simply add their values together. To add two negative numbers, add their values together and then subtract this sum from zero. For example, if you want to add -2 and -5, you would first add their values together to get -7. Then, you would subtract -7 from zero to get 7. The answer is positive because the signs of the two numbers cancel each other out.
To subtract a negative number from a positive number, simply add the absolute value of the negative number to the positive number. For example, if you want to subtract -5 from 3, you would first take the absolute value of -5 which is 5. Then you would add 5 + 3 to get 8. The answer is positive because the signs of the two numbers cancel each other out.
It is also possible to subtract a positive number from a negative number. In this case, you would simply take the absolute value of the positive number and subtract it from the absolute value of the negative number. For example, if you want to subtract 5 from -3, you would first take the absolute value of 5 which is 5. Then you would subtract 5 – 3 to get -2.
When to use negative numbers
Negative numbers are numbers that are less than zero. They are often used to represent a debt or something that is below zero on a scale. For example, if you have -5 dollars in your bank account, you owe 5 dollars.
Negative numbers are also used in temperature. For example, if the temperature outside is -5 degrees Celsius, it is colder than 0 degrees Celsius.
Negative numbers can be added and subtracted just like positive numbers. However, you need to be careful when doing so.
If you are adding two negative numbers together, the result will be a negative number. For example, if you add -5 and -3 together, the result will be -8.
If you are subtracting a negative number from a positive number, the result will be a positive number. For example, if you subtract -3 from 5, the result will be 8.
It is important to remember these rules when working with negative numbers so that you can get the correct answer!
What are negative numbers?
Negative numbers are numbers that are less than zero. They are written with a minus sign in front of them. For example, -5 is a negative number.
Negative numbers are used in many different situations. For example, when subtracting a larger number from a smaller number, the result will be a negative number. Or, when taking a temperature reading, negative numbers may be used to indicate below freezing temperatures.
Adding and subtracting negative numbers can be confusing for some people. The key is to remember that a minus sign in front of a number means that the number is subtracted from the total. So, when adding two negative numbers together, the answer will be even more negative since both numbers are being subtracted from the total.
How to add and subtract negative numbers
Adding and subtracting negative numbers can be a little tricky, but it’s important to know how to do it! Here are some tips:
When adding two negative numbers together, the answer will always be a negative number. So, if you’re trying to add -5 and -3, the answer will be -8.
When subtracting a negative number from another negative number, the answer will be the difference between the two numbers (just like when you’re subtracting regular numbers). So, if you’re trying to subtract -5 from -3, the answer will be 2.
If you’re subtracting a negative number from a positive number, the answer will be the sum of the two numbers (again, just like when you’re subtracting regular numbers). So, if you’re trying to subtract -5 from 3, the answer will be 8.
Examples of adding and subtracting negative numbers
Adding and subtracting negative numbers can be a bit confusing, but it’s really not that difficult once you understand the concept. Here are a few examples to help you see how it works:
Let’s say you have two temperatures, one at 72 degrees Fahrenheit and one at -3 degrees Fahrenheit. To find the sum of these two numbers, you simply add them together: 72 + (-3) = 69.
Now let’s say you want to find the difference between those same two temperatures. To do this, you would subtract the lower number from the higher number: 72 – (-3) = 75.
As you can see, when you’re dealing with negative numbers, you just have to keep in mind which number is larger. The rest is just like any other addition or subtraction problem!
When to use negative numbers in real life
Negative numbers are often used in real life to represent debt or a decrease in value. For example, if someone owes you $50, they would have a negative balance of -$50. Similarly, if the stock market decreases by 50 points, it would be represented as -50.
negative numbers can also be used to represent temperatures below zero. For example, if the temperature outside is -10 degrees Celsius, that would be equivalent to 14 degrees Fahrenheit.
Conclusion
Adding and subtracting negative numbers can be a tricky concept for some students to grasp. However, with a little practice, it can become much easier. We hope that these tips have helped you understand how to add and subtract negative numbers. If you still need some help, there are plenty of resources available online or from your math teacher. With a little extra effort, you’ll be adding and subtracting negative numbers like a pro in no time!
