Answer 2

Answer:

3

Step-by-step explanation:

So we have the expression:

$39\div(2+1)-2\times(4+1)$

Recall the order of operations or PEMDAS:

P: Parentheses

E: Exponents

M/D: Multiplication and Division (Whichever First)

A/S: Addition and Subtraction (Whichever First)

Thus, first do the operations inside the parentheses:

$39\div(2+1)-2\times(4+1)\\=39\div(3)-2\times(5)$

Now, do division and multiplication:

$39\div(3)-2\times(5)\\=13-2\times5$

And the multiplication:

$13-2\times5\\=13-10$

And finally, subtract:

$13-10\\=3$
