4. For example: Firstly, line the numbers up correctly and add a decimal point in the answer bar: U t h 3 7 7 + 4 2 8

5. U t h 3 7 7 + 4 2 8
Then add up the hundredths:

6. U t h 3 7 7 + 4 2 8
Then add up the hundredths:
7 + 8 = 15

7. U t h 3 7 7 + 4 2 8 5 Then add up the hundredths: 7 + 8 = 15
The 5 is written in the hundredths column 5

8. U t h 3 7 7 + 4 2 8 5 Then add up the hundredths: 7 + 8 = 15
The 5 is written in the hundredths column and the 1 is carried into the tenths column and written below the answer bar. 5 1

9. U t h 3 7 7 + 4 2 8
Now add up the tenths: 5 1

10. U t h 3 7 7 + 4 2 8
Now add up the tenths:
= 10 tenths 5 1

11. U t h 3 7 7 + 4 2 8 5 Now add up the tenths: 7 + 2 + 1 = 10 tenths
The 0 is written in the tenths column 5 1

12. U t h 3 7 7 + 4 2 8 5 Now add up the tenths: 7 + 2 + 1 = 10 tenths
The 0 is written in the tenths column and the 1 is carried into the UNITS column and written below the answer bar. 5 1 1

13. U t h 3 7 7 + 4 2 8
Finally, add up the units: 5 1 1

14. U t h 3 7 7 + 4 2 8
Finally, add up the units:
= 8 5 1 1

15. U t h 3 7 7 + 4 2 8 8 5 Finally, add up the units: 3 + 4 + 1 = 8
The 8 is written in the Units column 8 5 1 1

16. U t h 3 7 7 + 4 2 8 8 5 1 1
