Solve the Addition: 693 + 705 Three-Digit Sum Calculation

Let's solve the problem by performing the addition step-by-step:

We are given the numbers $693$ and $705$. Our goal is to add these two numbers together.

Step-by-step Addition:

• Step 1: Align the numbers by place value:
•     $693$
• + $\, 705$
• ────────
• Step 2: Add the units column (rightmost digits): $3 + 5 = 8$.
• Step 3: Add the tens column: $9 + 0 = 9$.
• Step 4: Add the hundreds column: $6 + 7 = 13$. Since we have a two-digit result here, we place the $3$ in the hundreds column and carry over the $1$ to the next leftmost position, which would be the thousands column in this case

After carrying over the addition results, our final number will be:

•     $693$
• + $\, 705$
• ────────
•     $1398$

Therefore, the sum of $693$ and $705$ is $1398$.
