to subtrct integers ,rewrite as adding opposites and use the rules for addtion of integers..
Adding integers, if they have the same sign, add their absolute values and keep the same sign. Subtracting, change the sign of the 2nd number and the add using rules of addition. Multiplying and dividing, Divide the absolute values, if the signs are the same the answer is positive, if the signs are different the answer is negative.
What is the definition of Adding and Subtracting Like Fractions

adding and subtracting integers is when you add and minus 2 numbers
Integers are whole numbers, both positive and negative. Therefore, adding and subtracting integers would be adding and subtracting whole numbers. Examples: 8+2 -8+2 8-2 -8-2
I would think that the commonality of adding and subtracting integers is that the answer itself will always be an integer. In other words, the answer is always gonna be a "whole number".
When subtracting integers, the result is equivalent to adding the opposite of the integer being subtracted. Specifically, for any integers ( a ) and ( b ), the statement ( a - b ) can be rewritten as ( a + (-b) ). This means that subtracting an integer is always the same as adding its negative.

No- adding negative numbers is like adding positive numbesr , except the answer is negative.
Let x and y be two integers. x - y = x + (-y)
1+1 = 2 2-1 = 1
Adding and subtracting integers is a specific case of adding and subtracting rational numbers, as integers can be expressed as rational numbers with a denominator of 1. The fundamental rules for adding and subtracting integers—such as combining like signs and using the number line—apply similarly to other rational numbers, which can include fractions and decimals. The operations are governed by the same principles of arithmetic, ensuring that the properties of addition and subtraction, such as commutativity and associativity, hold true across both integers and broader rational numbers. Thus, mastering integer operations provides a solid foundation for working with all rational numbers.
They aren't. The rules are the same as those for adding/subtracting or multiplying integers. Just be careful of the decimal point's location.
It's pretty much the exact same. Subtracting is the same as adding a negative number. Foe example, five minus three is the same as five plus negative three.
