Add 945 and 55: Vertical Addition Practice

To solve this vertical addition problem, we need to add 945 and 55. Let's work through this step-by-step, adding from right to left (from the ones place to the hundreds place).

Step 1: Set up the problem with proper alignment
We align the numbers by place value:

$\begin{aligned} &945 \\ +&~~55 \\ \hline \end{aligned}$

Step 2: Add the ones column
In the ones place, we have $5 + 5 = 10$.
Since 10 equals 1 ten and 0 ones, we write 0 in the ones place and carry 1 to the tens column.

Step 3: Add the tens column
In the tens place, we have $4 + 5 = 9$, plus the carried 1, giving us $9 + 1 = 10$.
Since 10 equals 1 hundred and 0 tens, we write 0 in the tens place and carry 1 to the hundreds column.

Step 4: Add the hundreds column
In the hundreds place, we have $9 + 0 = 9$ (since 55 has no hundreds digit), plus the carried 1, giving us $9 + 1 = 10$.
Since 10 equals 1 thousand and 0 hundreds, we write 0 in the hundreds place and carry 1 to the thousands column.

Step 5: Write the thousands digit
The carried 1 becomes our thousands digit.

The complete addition looks like this:

$\begin{aligned} &\,^1\,^1\,^1 \\ &945 \\ +&~~55 \\ \hline &1000 \end{aligned}$

Therefore, the sum of 945 and 55 is $1000$.
