(1,850

1st you have to multiply -462 * 2 = 924 because it is in the prentheses.

2nd you have to subtract 1,850 - 462 = 1388 because next in prentheses.

3rd you have to subtract 1388 - 924 = 464 becasue next in prentheses.

4th and finally you have to divide 464/2 = 232 because that is final step in the problem.

So the solution to the problem is 232.
