Question

$(+5)-(-3)-(+2)+(-6)-(-7)+(+4)-(-12)$

Explanation:

Step1: Rewrite with correct signs

$(-12) - (+4) + (-7) - (-6) + (+9) - (-3) - (+8) + (+5)$

Step2: Simplify sign operations

$-12 - 4 - 7 + 6 + 9 + 3 - 8 + 5$

Step3: Sum negative terms

$-12 - 4 - 7 - 8 = -31$

Step4: Sum positive terms

$6 + 9 + 3 + 5 = 23$
