Minutes column: Here, 45 + 33 =
78 min
Minutes column: We cannot subtract 55
from 35.
We borrow 1 h = 60 min
(60 + 35) = 95 min
Regrouping 78 min = 1 h 18 min
Write 18 m the minutes column,
carry
1 to the hour column.
Hours column: We add the hour
column, i.e., 5+7 + 1 = 13 h
95 - 55 = 40 min
Hours column: 6 - 3 = 3 h​
