Step-by-Step Solution

To solve the addition of $2789 + 456$ , we'll proceed with vertical addition:

Step 1: Align the numbers by their digits:
$\begin{array}{c} \phantom{0}2789 \\ +\phantom{0}456 \\ \underline{\phantom{0000}} \\ \end{array}$
Step 2: Start adding from the rightmost column (ones place):
$9 + 6 = 15$ . Write down $5$ and carry over $1$ to the tens place.
Step 3: Add the tens place:
$8 + 5 = 13$ , and add the carry over $1$ , getting $14$ . Write down $4$ and carry over $1$ to the hundreds place.
Step 4: Add the hundreds place:
$7 + 4 = 11$ , and add the carry over $1$ , getting $12$ . Write down $2$ and carry over $1$ to the thousands place.
Step 5: Add the thousands place:
Since we only have $2$ and a carry of $1$ , the result is $3$ .
Step 6: Compile the result across all columns:
$3245$

Therefore, the solution to the addition problem is $3245$ .
