Are you good at Maths:-)

People eat three times per day. How many times do they eat a week?

A candle burns after 15 minutes. How long it takes to burn 10 candles if they were lit at the same time?

We live in  2011 . What is the total sum  of these numbers?

How much?     2 + 2 – 2 + 2 – 2 + 2 – 2 + 2 – 2 + 2

Good luck :-)

  1. People eat 3*7=21 times in a week.
    All candles will burn out after 15 minutes as they were lit together ;-)
    The 2 line with -2 +2 ...... =4 (the first two digits)
    Very clever indeed. Thanx a lot.
    We didn't get the 2011 question. Can you explain?

  2. Dear Demi,
    You are really good at maths:-)

    You should say -what is the sum of these numbers?
