Complete the Equation: Finding the Missing Value in 1000 + □ = 1010

To solve this problem, we need to determine the missing number in the equation $1000 + \Box = 1010$. To find this missing number, we will convert the addition problem into a subtraction problem:

Step 1: We have the equation:

• $1000 + \Box = 1010$

Step 2: To find $\Box$, we can rearrange the equation by subtracting 1000 from 1010:

• $\Box = 1010 - 1000$

Step 3: Perform the subtraction:

• $1010 - 1000 = 10$

Therefore, the missing number is $\Box = 10$.

Thus, the solution to the problem is $\Box = 10$. Among the provided answer choices, this corresponds to choice 2.
