Adding Time Quickly!
is a very useful hack to add hours and minutes together:
try adding 2 hours and 44 minutes with 2 hours and 25 minutes.
lets put the hours and minutes together so that they form a number. We
will get 244 and 255
using the addition hack you learnt earlier add 244 to 225
+ 225 = 469
add 40 (this is a fixed addition step) to
469 to give you 509 (This is a compulsory step to be done so
for all addition of time.)
Since hour is always in single digit and minutes in double digit, you
should write your answer, which is 509, in the same way (509
= 5 + 09).
Thus, the answer is 5 hours and 09 minutes.
this trick with your friends and have fun adding time quickly!
