What value should come in place of questions (?) in the following equations?

$56\times 15÷3–83=?–139$

The correct option is 336.

To find the missing value in place of the question mark (?), we will simplify the left-hand side of the equation using the standard order of operations (BODMAS/PEMDAS rule), which prioritizes Division and Multiplication before Addition and Subtraction.

The given equation is:

$56\times 15÷3-83=?-139$

Step 1: Perform the division operation on the left-hand side.

$15÷3=5$

Substituting this back into the equation:

$56\times 5-83=?-139$

Step 2: Perform the multiplication operation on the left-hand side.

$56\times 5=280$

Substituting this result back:

$280-83=?-139$

Step 3: Perform the subtraction on the left-hand side.

$280-83=197$

Now the equation simplifies to:

$197=?-139$

Step 4: Solve for the question mark (?).

Add 139 to both sides of the equation to isolate ?:

$?=197+139$

$?=336$

Thus, the value that should come in place of the question mark is 336.
