3-5*(-1)/(1-3*(-1)) = 3 +5/(1 + 3) = 3 +5/4 = 3 + 1.25 = 4.25 (Ans.)

(3 - 5*(-1)) / (1 - 3*(-1))
= 8 / 4
= 2

3 - 5(-1) / [1 - 3(-1)]
The first thing to do is the parenthesis. So let's look at the braces. Inside we have a multiplication and a subtraction. So let's do the multiplication first:
-3 * -1 = 3
So what's left turns into an addition:
3 - 5(-1) / (1 + 3)
and then finish the addition:
3 - 5(-1) / 4
So now we have a subtraction, multiplication, and division. Multiplication and division are done at the same level, from left-to-right. So we do the multiplication first, then the division:
3 + 5 / 4
3 + 1.25
And finally, the addition:
4.25

(1-3*(-1)) = 1+3 = 4
