Please demonstrate how to solve this problem step by step using PEMDAS 3-5*(-1)/(1-3*(-1)) Thank you.?

3-5*(-1)/(1-3*(-1))

3 + 5/(1+3)

3 + 5/4

12/4 + 5/4

17/4

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+3] =

3+5/4 = 4.25

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

hint:

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