Solve Vertical Subtraction: 70 minus 14.4

To solve the subtraction $70 - 14.4$, we need to perform the following steps:

• Step 1: Convert $70$ to a decimal number for easier alignment, writing it as $70.0$.

• Step 2: Write the two numbers vertically, aligning to the right and with the decimal points:

$\begin{aligned} 70.0 \\ - \ 14.4 \\ \hline \end{aligned}$

• Step 3: Perform the subtraction starting from the rightmost digit.

• Step 4: Subtract tenths: $0$ (borrow if necessary) - $4$ becomes $10 - 4 = 6$, since we needed to borrow 1 from $7$, making it $6$.

• Step 5: Subtract whole numbers: $6 - 1 = 5$ and $7 - 1 = 5$ (remember we borrowed to balance the tenths).

Therefore, after the subtraction, we find that the solution is $55.6$.
