Let's add the numbers:
1. Starting with the units place:
- Add 9 (from 259), 0 (from 180), and 2 (from 542):
[tex]\[ 9 + 0 + 2 = 11 \][/tex]
- Write down 1 in the units place and carry over 1 to the tens place.
2. Next, the tens place:
- Add 5 (from 259), 8 (from 180), and 4 (from 542), and don't forget the carried over 1:
[tex]\[ 5 + 8 + 4 + 1 = 18 \][/tex]
- Write down 8 in the tens place and carry over 1 to the hundreds place.
3. Finally, the hundreds place:
- Add 2 (from 259), 1 (from 180), and 5 (from 542), and add the carried over 1:
[tex]\[ 2 + 1 + 5 + 1 = 9 \][/tex]
- Write down 9 in the hundreds place.
Combining these, we get the total sum:
[tex]\[ 981 \][/tex]
So,

\begin{array}{r}
