((15,3+3,7).2,8)-2,9=?

Grace [21]

Answer: $=50,3$

Step-by-step explanation:

For this exercise it is important to remember the multiplication of signs. Notice that:

$(+)(+)=+\\\\(-)(-)=+\\\\(-)(+)=-\\\\(+)(-)=-$

In this case you have the following expression:

$((15,3+3,7)2,8)-2,9$

The steps to solve it are:

Step 1: You must solve the addition inside the parentheses:

$((15,3+3,7)2,8)-2,9=((19)2,8)-2,9$

Step 2: Now you must solve the multiplication:

$=53,2-2,9$

Step 3: Finally, you must solve the subtraction. Therefore, you get:

$=50,3$
