Mastering Integer Addition Techniques

This video tutorial covers the rules for adding integers, focusing on cases with the same and different signs. It explains the algorithm for adding integers, including finding the sum for same signs and the difference for different signs. Examples are provided to illustrate these concepts, including how to handle absolute values and rearrange numbers for easier subtraction. The lesson concludes with a recap of the key rules.

What should you do when adding two integers with the same sign?

• Add the absolute values and keep the sign

• Subtract the absolute values

• None of the above

• Always result in a positive number

When adding integers with different signs, what should you do?

• Subtract the absolute values and keep the sign of the number with higher absolute value

• Subtract the smaller number from the larger and take the sign of the larger

• Add the numbers and ignore the signs

• None of the above
