Review and consolidate understanding of absolute value, addition, subtraction, multiplication, and division of signed numbers.
📖 Summary
- Absolute value = distance from zero.
- Adding same signs: add and keep sign.
- Adding different signs: subtract and keep larger sign.
- Subtracting: change to adding the opposite.
- Multiplying/Dividing: same signs = positive, different signs = negative.
