Study Notes
Basic Operations with Negative Numbers
- Subtracting a negative number is equivalent to addition; thus, ( 4 - (-9) = 4 + 9 = 13 ).
- For ( 15 - (-58) ), apply the same principle: ( 15 + 58 = 73 ).
- Adding two negative numbers: ( -21 + (-9) = -21 - 9 = -30 ).
- Adding a positive and a negative number: ( 16 + (-11) = 16 - 11 = 5 ).
Combined Expression Evaluation
- The overall expression ( 4 - (-9) + 15 - (-58) ) simplifies as follows:
- Start with ( 4 - (-9) = 13 ).
- Then calculate ( 15 - (-58) = 73 ).
- Combine results: ( 13 + 73 = 86 ).
- Final result of ( 4 - (-9) + 15 - (-58) ) is ( 86 ).
