5.0/2-2+3*2/4 please explain this question

Answer 1

5.0/2 - 2 + 3*2/4 # First we multiply and divide
== 2.5 - 2 + 1.5 # Then we sum and substract
== 2.0

Answer 2

To solve this problem consider the order of mathematical operations
Perform the multiplication and division operations of the equation before the addition or subtraction operations of that equation.

(5.0/2 - 2) = .5
Perform division
(5.02/2) equals 2.509

Subtract 2 from that answer
(5.02/2-2) equals .5

- - -

(3*2/4) = 1.5
Perform the multiplication
(3*2) equals 6

Divide that answer by 4
(3*2/4) equals 1.5

Add the results both equations
.5 + 1.5 = ans 2
