Revision: It looks like we're probably not going to make it to 100, but the bonus points are still on the table. Any ideas for how I should award them? –  Isaac Moses Oct 6 '10 at 14:22

Maybe let them be autoawarded. I suspect there are many more Jewish hundreds no one's thinking of. –  msh210 Oct 6 '10 at 14:43

Yeah! If we can't reach 100, we don't deserve 100 points![/drill sergeant voice] –  msh210 Oct 6 '10 at 19:03

If we don't make it to 100, I'll award this one to the best answer from whoever contributed the most relevant answers. –  Isaac Moses Oct 7 '10 at 17:30

$100 is the threshold value a Rabbi of mine suggested for determining whether a new garment deserves a "Shehecheyanu".

(Interestingly, he suggested the same threshold over many years, apparently not taking inflation into consideration. Perhaps the psychological value of that round number retains significance across inflation.)

100 cc is a k'betza according to the Chazon Ish, IINM. (As always, CYLOR.)

100 is the number of people Elisha fed with a small amount of food (M'lachim II 4:43). (I haven't checked the commentaries, so it could be that this is an example of the hyperbole mentioned above, but I doubt it. Note that Rabbi Aron Tendler seems to say it really means 100.)

Also the Gemara seems to assume that it's literal, because it uses this to calculate that Elisha had 2200 full-time students (Kesubos 106a). –  Alex Oct 7 '10 at 20:16

100 is a number used as an example of a very large number in rabbinic Hebrew, as in Rashi to D'varim 15:10 and as in "דוחה מאה תוכחות".‎

Isn't the "100" in that Rashi coming out of the Midrash, rather than the Torah? –  Isaac Moses Oct 7 '10 at 17:06

We find it used in Biblical Hebrew too - in Eccles. 6:3, "אם יוליד איש מאה". –  Alex Oct 7 '10 at 18:47

100 is the g'matriya of "מדון" (Rashi, Sanhedrin 7a).
