Adding Integers

In this section, we dig deeper into the topic of integers. We will begin with adding integers. How do we add two or more integers together? There are two scenarios to consider:
Adding Integers with the Same Sign:
1) Add the absolute values of the numbers: 2 + 4 = 6
2) Attach the common sign to the answer: the common sign is "-", so we end up with -6
(-2) + (-4) = -6
Adding Integers with Different Signs:
1) Subtract the smaller absolute value from the larger: 5 - 3 = 2
2) Attach the sign from the number with the larger absolute value: 5 has a larger absolute value, so our answer will be positive: 2
(-3) + 5 = 2
Adding Integers with the Same Sign:
- Add the absolute values of the numbers
- Attach the common sign to the answer
1) Add the absolute values of the numbers: 2 + 4 = 6
2) Attach the common sign to the answer: the common sign is "-", so we end up with -6
(-2) + (-4) = -6
Adding Integers with Different Signs:
- Subtract the smaller absolute value from the larger
- Attach the sign from the number with the larger absolute value
1) Subtract the smaller absolute value from the larger: 5 - 3 = 2
2) Attach the sign from the number with the larger absolute value: 5 has a larger absolute value, so our answer will be positive: 2
