3. 3. For example: 3.77 + 4.28 Firstly, line the numbers up correctly U 3 + 4 t 7 2 h 7 8
4. 4. For example: 3.77 + 4.28 Firstly, line the numbers up correctly and add a decimal point in the answer bar: U 3 + 4 t 7 2 h 7 8
5. 5. U 3 + 4 t 7 2 h 7 8 Then add up the hundredths:
6. 6. U 3 + 4 t 7 2 h 7 8 Then add up the hundredths: 7 + 8 = 15
7. 7. U 3 + 4 t 7 2 h 7 8 5 Then add up the hundredths: 7 + 8 = 15 The 5 is written in the hundredths column
8. 8. U 3 + 4 t 7 2 h 7 8 5 1 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.
9. 9. U 3 + 4 t 7 2 Now add up the tenths: h 7 8 5 1
10. 10. U 3 + 4 t 7 2 Now add up the tenths: 7 + 2 + 1 = 10 tenths h 7 8 5 1
11. 11. U 3 + 4 Now add up the tenths: 7 + 2 + 1 = 10 tenths The 0 is written in the tenths column t 7 2 h 7 8 0 5 1
12. 12. U 3 + 4 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. h 7 8 0 1 t 7 2 5 1
13. 13. U 3 + 4 1 h 7 8 0 Finally, add up the units: t 7 2 5 1
14. 14. U 3 + 4 1 h 7 8 0 Finally, add up the units: 3+4+1=8 t 7 2 5 1
15. 15. U 3 + 4 Finally, add up the units: 3+4+1=8 The 8 is written in the Units column t 7 2 h 7 8 8 0 5 1 1
16. 16. U 3 + 4 t 7 2 h 7 8 8 0 5 1 1
