Here are the solutions to the subtraction problems:

:

\begin{array}{r} 801 \\ - \quad 778 \\ \hline \end{array}

Subtract the ones column.
We cannot subtract 8 from 1, so we borrow from the tens place. Since the tens place is 0, we borrow from the hundreds place. The 8 in the hundreds place becomes 7. The 0 in the tens place becomes 10, then lends 1 to the ones place, becoming 9. The 1 in the ones place becomes 11.
$11 - 8 = 3$
Subtract the tens column.
The 0 in the tens place became 9.
$9 - 7 = 2$
Subtract the hundreds column.
The 8 in the hundreds place became 7.
$7 - 7 = 0$
The result is:
$\begin{array}{r} 801 \\ - \quad 778 \\ \hline \boxed{\textbf{23}} \end{array}$
:
$\begin{array}{r} 976 \\ - \quad 484 \\ \hline \end{array}$
Subtract the ones column.
$6 - 4 = 2$
Subtract the tens column.
We cannot subtract 8 from 7, so we borrow from the hundreds place. The 9 in the hundreds place becomes 8. The 7 in the tens place becomes 17.
$17 - 8 = 9$
Subtract the hundreds column.
The 9 in the hundreds place became 8.
$8 - 4 = 4$
The result is:
$\begin{array}{r} 976 \\ - \quad 484 \\ \hline \boxed{\textbf{492}} \end{array}$
