An integer is a numerical value that can be expressed as a whole number, including both positive and negative values. Adding two integers involves adding their numerical values.
Process:
Add the two integers together.
Write the answer in the same order as the integers, with the signs indicating the order of addition (from left to right).
If the sum is negative, write it with a minus sign in front of the numbers.
Examples:
5 + 3 = 8 (add 5 and 3, starting from left to right)
10 - 2 = 8 (subtract 2 from 10, starting from left to right)
7 + (-4) = 3 (add 7 and -4, starting from left to right)
Additional notes:
When adding two negative integers, they are added in the opposite order, starting from right to left.
The answer to addition is always an integer.
Adding the same integer to itself will always result in 0, as adding 5 + 5 is the same as adding 0 + 5.
We can also add positive and negative integers using a different method called subtraction.
By following these steps and understanding the process, students can learn to add integers effectively and gain a deeper understanding of the mathematical concept
