Answer:
The answer is -87
Step-by-step explanation:
This problem bothers on the well we understand how to solve expressions using "minus" operators
Given the expression
−28−47−12
Let's begin by solving the first two terms
Hints: using monetary terms say in dollars
MINUS = OWING
PLUS = HAVING
so in this case we are owing
$28, $47 and $12
We are owing altogether $87
Now Mathematically
-(28+47+12)
-(87)
=-87
