Solve the Equation: Finding the Missing Number in 1550 + □ = 1750

To solve this problem, we'll follow these steps:

• Step 1: Identify the given numbers in the equation $1550 + \Box = 1750$.
• Step 2: Use the subtraction formula to find the missing number: $\Box = 1750 - 1550$.
• Step 3: Perform the calculation. Calculate $1750 - 1550$.

Now, let's work through each step:

Step 1: The given equation is $1550 + \Box = 1750$.

Step 2: We apply the subtraction formula: $\Box = 1750 - 1550$.

Step 3: Perform the calculation:

$1750 - 1550 = 200$.

This calculation tells us that when 200 is added to 1550, the result is 1750.

Therefore, the solution to the problem is $200$.
