Help pls i don't know where to put the pharenteses this is the equation
Brut [27]

Answer:

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

Step-by-step 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
