-You must memorize
-To add 2 integers with different signs, find the difference of their absolute value
-To subtract an integer, add it's opposite
Subtracting a negative is the same as adding the equivalent positive. For example, subtracting minus 10 is the same as adding 10.
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.

When subtracting negative numbers change the subtraction sign to a plus and change the second number (which would appear to be positive) to a negative. ex. -14 - 7=?/-14 + -7= -21 When adding negative numbers just add them as they appear. ex. -2 + -5= -7

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
a difference
You subtract a polynomial by adding its additive inverse. For example, subtracting (x - y) is the same as adding (-x + y). Alternately, you can simply subtract similar terms - that is, subtract the coefficients (the numbers) for terms that have the same combination of variables.
