Answer:
6
Explanation:
Remember PEMDAS
P=Parenthesis. Solve what's inside all sets of parenthesis.
2-12=-10
Now the equation looks like: 2.8/1.4-2/5(-10)
E=Exponents. This equation has none, so we can move on.
MD=Multiplication and Division from left to right.
2.8/1.4=2
New equation: 2-2/5(-10)
2/5=0.4
New equation: 2-0.4(-10)
0.4(-10)=-4
New equation: 2-(-4)
AS=Addition and Subtraction from left to right.
2-(-4)=6
