To solve this expression, we follow the order of operations, which is PEMDAS (parentheses, exponents, multiplication/division (from left to right), addition/subtraction (from left to right)).
First, simplify inside the parentheses:
14 - 6 - (-15) - |18| + (-7)
Next, simplify the absolute value:
14 - 6 - (-15) - 18 + (-7)
Now, solve the subtraction inside the parentheses:
14 - 6 + 15 - 18 - 7
Next, solve the addition and subtraction from left to right:
(14 - 6) + 15 - 18 - 7
8 + 15 - 18 - 7
23 - 18 - 7
5 - 7
-2
The final answer is -2.
14-6-(-15)-|18|+(-7)
