Solve the Subtraction Problem: 72101 - 1400

To solve the subtraction problem, follow these steps:

• Step 1: Align the minuend $72101$ and the subtrahend $1400$ by their place values.

• Step 2: Subtract each digit starting from the rightmost side (units place).

Let's perform the subtraction:

1. Units place: $1 - 0 = 1$ 2. Tens place: $0 - 0 = 0$ 3. Hundreds place: $1 - 4$ requires borrowing. Borrow 1 from the thousands place, changing the $2$ in thousands to $1$, making it: - Hundreds place becomes $11 - 4 = 7$. 4. Thousands place: After borrowing, the thousands place becomes $2 - 1 = 1$. 5. Ten-thousands place: $7 - 0 = 7$.

Thus, the subtraction is performed as follows:

$72101$
$- \phantom{0}1400$
__________
$70701$

Therefore, the result of the subtraction is $70701$.
