Grammar Notes for Dialogue 4
Large numbers (10,000 to 100,000,000)
 

The Western system segments large numbers in groups of 3 digits: XXX, XXX, etc. In Japan, the large numbers used to be segmented in groups of 4 digits: XXXX, XXXX, etc. This segmentation closely conforms to the way Japanese pronounce large numbers as shown below. However, as the Western system of segmenting large numbers has been adopted in Japan, the close connection between mathematical and linguistic expressions has been lost.

The particle から normally marks the originating point of motion or the beginning point of time. It can also be used to refer to the departing point from which some value changes (prices, for example).

ねだんは 1000円からです。 The price is from 1000 yen (and above).

cf. まで can also be used to mark the ending point of change.

ねだんは 1000円までです。 The price is up to 1000 yen.
Aくなります (Change of states)
 

The English pattern /become + adjective/ (e.g., "become/get old," "become/get expensive," "become/get interesting," etc.) can be expressed by the pattern /い-adjectiveく+ なります/ in Japanese.

(がつ)になって、さむく なりました
  January came, and (then) it got cold.

Compare this pattern with the pattern /な-adjective に+ なります/ or /N に+ なります/.
