We came to a building material store, buy nails for assembling floors. According to estimates, we needed about 1,000 pieces. Nails are sold by weight - hence the question, how to buy a thousand? Weigh 10 pieces and multiply by 100. We get about 1000.
We approach the seller and say:
You need a thousand nails like that.
Seller: What am I going to count for you?
Take 10 pieces and multiply by 100.
She takes the calculator and counts: 10 multiply by 100 (five seconds of silence).
I am a thousand.
She: Well what does that mean? How to weigh?
