Adding A Thousand Units to 3203: What’s the Result?

To solve this problem, we must add 1000 to the number 3203.

Let's break it down step-by-step:

• Step 1: Identify the given number, which is 3203.
• Step 2: Add 1000 to this number. This means the digit in the thousands place increases by 1 (since 1000 is equivalent to adding 1 to the thousands place).
• Step 3: Perform the addition: $3203 + 1000 = 4203$.

Thus, the number we are left with after adding a thousand units is $4203$.
