To solve this problem, we'll follow these steps:
Step 1: Align the numbers vertically based on their place values:
+
Step 2: Start adding from the rightmost column (units place):
6 (from 456) + 4 = 10.
The result is 10, so we place 0 in the units place under the line, and carry over 1 to the next column (tens place).
Step 3: Move to the tens place, including the carry over:
5 (from 456) + 0 (from 004) + 1 (carry over) = 6.
Place 6 in the tens place under the line.
Step 4: Move to the hundreds place:
4 (from 456) + 0 = 4.
Place 4 in the hundreds place under the line.
The complete sum would look like this:
+
Therefore, the solution to the problem is , which corresponds to choice 4.

\( \begin{aligned} &90 \\ +& \\ &~~9\\ &\underline{\phantom{776}} & \\ \end{aligned} \)
When adding 6 + 4 = 10, you have 1 ten and 0 ones. The 1 ten belongs in the tens place, so you carry it over. Writing '10' in the ones place would be incorrect!
When a number doesn't have a digit in a certain place (like 4 has no hundreds), treat it as 0. So 4 becomes 004 when aligned properly.
Always align by place value! The ones digits go under ones, tens under tens, hundreds under hundreds. This keeps everything organized for accurate addition.
It's better to add from right to left (ones, then tens, then hundreds) because carrying works naturally this way. Left to right can cause confusion with carrying.
No problem! Just handle one column at a time. Add the column, write the ones digit, carry the tens digit to the next column, and repeat.
