Sure! Adding and subtracting integers is actually quite simple once you understand the basic rules. Here are the steps:
1. Identify the sign of each integer: Integers can be either positive (+) or negative (-).
2. For addition, if the signs are the same (both positive or both negative), simply add the numbers together and keep the sign.
For example:
- (+3) + (+2) = +5
- (-4) + (-1) = -5
3. For addition, if the signs are different, subtract the smaller number from the larger number and keep the sign of the larger number.
For example:
- (+3) + (-2) = +1
- (-4) + (+1) = -3
4. For subtraction, change the sign of the second number or simply add the opposite. This means that subtraction can be turned into addition.
For example:
- (+3) - (+2) can be rewritten as (+3) + (-2) = +1
- (-4) - (-1) can be rewritten as (-4) + (+1) = -3
That's it! Just remember the rules and practice a few examples, and you'll get the hang of adding and subtracting integers in no time.

Can u make a simple way to memorize thhis stuff, maybe a phrase or something
Absolutely! Here is a useful phrase to help you remember the rules for adding and subtracting integers:
"For like signs, just add; for different signs, find the difference."
Let's break it down:
1. "For like signs": This refers to when both integers have the same sign (either both positive or both negative). In this case, you simply add the numbers together.
2. "Just add": This reminds you to add the numbers without changing their signs.
Example: (+5) + (+3) = +8
3. "For different signs": This refers to when the signs of the integers are different (one positive and one negative). In this case, you subtract the smaller number from the larger number and keep the sign of the larger number.
4. "Find the difference": This reminds you to find the difference between the larger and smaller numbers.
Example: (+5) + (-3) = +2
These phrases can act as memory aids to easily recall the process for adding and subtracting integers. Practice a few examples using this phrase, and soon it will become second nature to you!
