Question

Find:

$-71-(-49)$

Answer 1

To subtract the subtrahend from the minuend, we need to add the additive inverse of subtrahend to the minuend.

Here, the minuend is $-71$ and the subtrahend is $-49$.

$-71-(-49)$$=-71+(additiveinverseof-49)$

$=-71+49$ (As the additive inverse of $-49$ is $49$).

To add the integers with different signs we have to subtract their absolute values and give the sum the sign of greater absolute value.

$=-(71-49)$

$=-22$.

Final Answer: $-71-(-49)$$=-22$
