Question

$-13+(-69)+57-(-89)-(53+(-49\left)\right)=\text{\_\_\_}$

• A. 50
• B. 60
• C. 70
• D. 80

Answer 1

The correct option is B

60

$-13+(-69)+57-(-89)-(53+(-49\left)\right)$

$=-13-69+57+89-(53-49)$

$=-13-69+57+89-53+49$

On grouping all the positive terms and negative terms together, we get:

$=(-13-69-53)+(57+89+49)$

$=-135+195$

$=60$
