1.Learn a shortcut technique to add time
Add hours and minutes together and faster
For example Let's add 2 hr and 45 minutes and 3 hr 15 minutes.
Step 1 Make the 2 hr 45 minutes into one number, which will give 245
Step 2 Do the same for the other number, 3 hours 15 minutes, giving 315
Step 3 Add these two numbers together.245 + 315 = 560
Step 4 Now, add the time constant of 40.No matter what the hours and minutes are,just add the 40 time constant to the sub total.560 + 40 = 600
Step 5 Our answer is 6 hrs !Try any other..Have fun!
Note: You can also make a project on such type of short cut techniques.Take help from vedic mathematics .
2.What does lbs stand for? Why is it the abbreviation for pounds?
The Latin word for pound is LIBRA, and that word was once used in English when referring to money. Apparently our word "pound" comes from the Latin word "pondo" which means weight; the Latin expression seems to have been "libra pondo" for "a pound in weight" (as opposed to a pound in money). The Italian monetary unit, the lira, as well as the British pound were coins that were once equivalent to a pound of a precious metal.
