The sum of two integers is always what type of number?

When considering the sum of two integers, it is essential to understand the properties of integers. Integers are whole numbers that can be positive, negative, or zero, but they do not include fractions or decimals.

When you take two integers and add them together, the result will always be another integer. This is due to the closed property of addition within the set of integers, which states that the sum of any two integers will produce another integer. For example, if you take 3 and -5, their sum is -2, which is still an integer.

This property holds true regardless of the specific integers involved, meaning the outcome will consistently be an integer. Other types of numbers, such as fractions or decimals, cannot result from adding two integers, reinforcing that the correct answer is indeed that the sum is an integer.
