To solve this problem, we need to add the two numbers, and , using vertical addition.
Step-by-step solution:
Step 1: Add the units place digits: . Here, is written in the units place, and we carry over to the tens place.
Step 2: Add the tens place digits: . As there was a carry from the previous step, the result is in the tens place.
Step 3: Add the hundreds place digits: . There is no carry to add, so the hundreds place remains .

Carrying means when two digits add up to 10 or more, you write the ones digit and move the tens digit to the next column. For example, means write 4 and carry 1.
We start with the units place (rightmost column) because any carrying affects the next column to the left. This ensures we handle all carries correctly as we move left.
When one number doesn't have a digit in a column, treat it as zero. In this problem, 8 has no hundreds or tens digits, so we add and .
Double-check by adding horizontally: . Also verify each column: units (6+8=14), tens (1+0+carry=2), hundreds (7+0=7).
Your answer will be wrong! Always circle or mark the carry digit above the next column so you don't forget to add it. Practice makes this automatic.
