Answer:

[39/(15-2)]-(2×9) = -15

Step-by-step explanation:

[39/(15-2)]-(2×9)

Let’s start with this part : 39/(15-2)

According to the order of operations parentheses comes before division

then

39/(15-2) = 39/(13) = 39/13 = 3

We get [39/(15-2)]-(2×9) = 3 - (2 × 9)

…………………………………………

Calculating 3 - (2 × 9)

According to the order of operations parentheses and multiplication comes before division

Then

3 - (18) = 3 - 18 = -15

Thus

[39/(15-2)]-(2×9) = -15
