MATHS FACTS TO BRIGHTEN UP A                                RAINY DAYS

1.Dividing by zero once put a US Navy Warship out of action.

In 1997 an unwitting crew member onboard the USS Yorktown wrongly entered a zero into one of the ships computers. This caused the ship’s software to divide by zero, meaning that it was stranded and unable to move for over two hours.

2. The number 0.999999….. is exactly equal to 1

Proof: Let x=0.9999…

Then 10x = 9.9999…

10x-x =(9.9999…)-(0.9999…)

9x=9

x=1
