The correct answer is

310

Apply the given substitutions to each operator: + becomes -, - becomes ×, × becomes ÷, and ÷ becomes +.

The expression 33 - 7 ÷ 81 + 44 × 22 therefore rewrites as 33 × 7 + 81 - 44 ÷ 22.

Using the BODMAS order, first do the multiplication and division: 33 × 7 = 231 and 44 ÷ 22 = 2.

The expression now reads 231 + 81 - 2.

Compute the addition and subtraction: 231 + 81 = 312 and 312 - 2 = 310.

Hence, the value in place of the question mark is 310.
