Help pls i don't know where to put the pharenteses this is the equation

15 - 25 x 2.4 + 7 - 3 x 2= -16

Answer 1

{15 - {(25 x 2.4) + 7}}- (3 x 2) = -16

Explanation:

15 - 25 x 2.4 + 7 - 3 x 2= -16 is the given equation.

Now by the rule of BODMAS:

here B = Bracket, O means Of, D means Divide, M means Multiplication , A means Addition and S means Subtraction.

So, according to this order start putting brackets.

first operation is multiplication, second is addition and then subtraction.

⇒ 15 - 25 x 2.4 + 7 - 3 x 2 = {15 - {(25 x 2.4) + 7}}- (3 x 2)

Hence, {15 - {(25 x 2.4) + 7}}- (3 x 2) = -16
