Question

Find the value of $25-\left[\left(-13\right)+\left(15\right)\right]$

Answer 1

Let's find the value of $25-\left[\left(-13\right)+\left(15\right)\right]$

If the given numbers are of unlike signs, let's subtract the absolute values directly and give the sign of the largest absolute valued integer to the result.

Let's add $-13+15=2$

Now it's $25-\left[2\right]$

Let's take the additive inverse of $2=(-2)$.

So,

$25-\left[2\right]=25+\left[-2\right]$

$=23$

Hence, the answer is $23$
