Subtract 106 from 404: Vertical Format Solution

Let's solve the subtraction problem $404 - 106$ step-by-step:

• Align the numbers vertically by their place values:
• $\begin{array}{c} \phantom{0}404 \\ -106 \\ \end{array}$
• Subtract starting from the rightmost column (ones):

The ones column: $4 - 6$ requires borrowing.

• We need to borrow from the tens column. However, the tens column in 404 has a zero, so we proceed to the hundreds column.
• Borrow 1 from the hundreds column, turning 4 into 3, and the tens zero into 10.
• Then, borrow again from the new tens column (10), turning it into 9 and adding 10 to the ones, making it 14.
• Subtract: $14 - 6 = 8$.
• Subtract the tens column:

Now, subtract the tens column: $9 - 0 = 9$.

• Subtract the hundreds column:

Finally, for the hundreds column: $3 - 1 = 2$.

So, putting it all together, the result of subtracting $106$ from $404$ is $298$.

Therefore, the solution to the subtraction problem is $298$.
