About this worksheet
Sums with negative numbers, written with brackets as in school books: (−7) + 5. Every sum has at least one negative number.
Tips for parents and teachers
- Use a number line for adding and subtracting. Adding a negative number moves left; subtracting a negative number moves right.
- Subtracting a number is the same as adding its opposite: 3 − (−4) = 3 + 4.
- For multiplying and dividing: same signs give a positive answer, different signs give a negative answer.
