Counting in Japanese

Ok...i can understand 1's, 10's, 100's, 1000's, 10,000's (ichi, juu, hyaku/byaku/pyaku, sen/zen, man) in japanese.....but....once it gets past 99,999...i dont know how to count higher (1,000,000 etc etc). Hope this isnt confusing so far, but, what comes after 10,000(man)? isnt there a pattern or something?

十万 ＝100,000
百万 ＝1,000,000
千万 ＝10,000,000
一億 ＝100,000,000
十億 ＝1,000,000,000
百億 ＝10,000,000,000
千億 ＝100,000,000,000
