Numbers 1000～

We call 1,000 “sen”.

For example, we call 2,354 as “ni-sen-sann-byaku-go-jyuu-yon”.

Please, do the simple math.  2,354 = 2 x 1,000 + 3 x 100 + 5 x 10 + 4 and read the numbers without “+”　and “x”.

Please, pay attention to 1,111 becasue 1,111 = 1,000 + 100 +10 +1, not 1,111 = 1 x 1,000 + 1 x 100 + 1 x 10 +1

Therefore, the pronunciation is “sen-hyaku-jyuu-ichi”, not “ichi-sen-ichi-hyaku-ichi-jyuu-ichi”.

Numbers 100～

We say 100 as “hyaku”.

101: hyaku-ichi

Since 101=100+1, you can simply read 100 and 1 without “+”

In the same way,

102: hyaku-ni

103: hyaku-san

104: hyaku-yon

110: hyaku-jyuu

111: hyaku-jyuu-ichi  *111=100(hyaku)+10(jyuu)+1(ichi)

How about 213?

Since 243=2×100+4×10+3

You can merely read 2(ni),100(hyaku), 4(yon),10(jyuu) and 3(san)

Ni-hyaku-yon-jyuu-san

Did you get this?
