The correct answer is

50

Equation Calculation Solved

The question asks us to determine the value represented by the question mark (?) in a sequence of arithmetic operations. We need to carefully calculate the result of the given expression.

The equation provided is:

$$1156 + 984 - 2256 + 166 = ?$$

Steps for Arithmetic Equation

To find the missing number, we will solve the equation step-by-step, performing the addition and subtraction operations from left to right as they appear.

Add First Numbers

The first step involves adding the initial two numbers, 1156 and 984:

$$1156 + 984 = 2140$$

So, the equation simplifies to: $$2140 - 2256 + 166 = ?$$

Subtract Second Number

Next, we subtract 2256 from the result obtained in the previous step (2140):

$$2140 - 2256 = -116$$

The equation now becomes: $$-116 + 166 = ?$$

Add Final Number

The final step is to add 166 to the result from the subtraction step (-116):

$$-116 + 166 = 50$$

Missing Number Value Found

By following these steps systematically, we find that the value which should replace the question mark (?) in the equation is 50.
