The expression given is
6(31) + 6(4) - 6(15)
Now we already know the rule of BODMAS ( Bracket of division, multiplication, addition, substration).
So in the given equation we have to first multiply the numbers within the bracket with the number outside the bracket and then proceed to the next step.
So
188 + 24 - 90
Now we have to add first as per the rule of BODMAS. So the epression comes down to:
212 - 90
= 122
So the correct answer to the expression is 122.
