Mareh Mekomos:

Begin on 45B, at the two dots amar Rava, on the sixth to last narrow line. Learn the gemara until the very end of the amud (until Rav Zeira on the top of 46a. See Rashi and tosfos dh Rav Zvid and dh ha. On the first gemara that discusses one being mafsik for two, see Rashi carefully in dh echad mafsik leshnayim. See Rabeinu Yonah (page 33a dh de’ayn) that says a different pshat in the gemara. See Rosh siman 7 that brings the machlokes Rashi and Rabeinu Yonah and Ravaad. Do Rabeinu Yonah and Ravaad argue? The Rosh adds an important detail in Rashi, see Ma’adanei Yom Tov on the bottom of the Rosh sk alef that brings a source to this from the gemara. Rambam hilchos Brachos perek 7 halacha 6 seems to have a third pshat, see Kesef Mishna there. See Divrei Chamudos on the Rosh sk 17 that brings Rashba that says what the Ravaad that is quoted in the Rosh says. The Rashba quoted there brings a big chidush from Rav Hai gaon. See Mishna Brura siman 200 sif 1 sk 5 that brings Bach and those who argue. See also Shar Hatzion there sk 7 and Biur Halacha dh ad.

Begin on 45a, tistayim, 10 lines from the top. Learn until the two dots 6 lines before the end of the narrow lines. See Rashi. After learning the whole gemara, see the second half of tosfos dh shani, that discusses if one can be motzi a person with a bracha if the one listening doesn’t understand loshon hakodesh. See Shulchan Aruch siman 193 sif 1 that paskens like tosfos that one who doesn’t understand is not yotzei. See Mishna Brurah sk 5 that discusses how is a person yotzei listening to kidush if he doesn’t understand. See Biur Halacha dh aino yotzei that discusses if there are three people in a mezumen if one can be yotzei without understanding and brings from the Birchas Avrohom. Why should a mezumen be different? On the gemara about the third person who left that he can answer from a distance, see Rambam hilchos brachos perek 5 halacha 13. According to the Rambam, can one be yotzei bentsching that way? See Meiri here dh shlosha sheachlu that brings a machlokes about this. See Shulchan Aruch siman 194 sif 2 with Mishna Brura sk 8 that brings Rambam.

Begin at the two dots on 45a, on the last narrow line. Learn the gemara and Rashi until 45b, tistayem derav, 10 lines from the top. What is the explanation in the opinion that says that two are not allowed to make a mezuman, what is wrong with making a mezuman that it is not permitted? See tosfos dh im that should answer this question. See Pnei Yehoshua on the tosfos (dh im, at the beginingg of the piece). On that tosfos, what is a nafka mina between the two answers of tosfos? What is the gemaras proof from ayn reshayin lechalek that two cannot be mezamen? See tosfos dh shlosha. On the gemara that discusses ladies making a mezuman, see tosfos dh shani that explains why we don’t have this minhag nowadays. See, however, Rabeinu Yonah (33a dh nasim and the beginning of dh nireh) that argues on tosfos and says that ladies are obligated to be mezamen. See Shulchan Aruch siman 199 sif 7 with Biur Hagra and Mishna Brura siman 199 sk 16 with Shar Hatzion sk 6 and Biur halacha dh nashim.

Begin on 45a at the beginning of the gemara and learn until the two dots at the last narrow line. See Rashi and tosfos dh bekolo. Is zimun min hatorah or miderbanan? See Ritva here dh deksiv and Meiri dh veinyan zimun. When the gemara asks mena hani mili about zimun, which aspect of zimun is it asking about? See Rashi dhmena hani mili with Pnei Yehoshua on the Rashi. On the gemara that learns out of Moshe that a metargem may not raise his voice above the Rav, what is the proof from the passuk? See tosfos dh bekolo and see Mahrsha on tosfos and in Chidushei Agados. See the shidush of the Rambam in this din in hilchos talmud torah perek 4 halacha 3. The gemara appears to contradict the Rambam? Regarding the question that we spoke about, what should one with regards to zimun if he wants to leave a chasunah early, Igros Moshe (Orach Chaim siman 56) discusses this.

Mareh Mekomos:

Begin on 45a at the mishna. Learn the mishna with Rashi and tosfos dh shlosha. What is Demai and Kusi? See Rav (Bartenura) in mishnayos that explains these two terms. What does the end of mishna mean when it says “ad kamah mezamnim”? See Rashi dh ad kamah. see Pnei Yehoshua on Rashi dh shamash that explains why the mishna says that the shamash ate a kazayis, something that the mishna doesn’t mention earlier. He also explains Rashi dh mezamnim. After learning tosfos dh shlosha, there should be some clarity regarding the question, what is considered eating together in order to be mitztaref for a mezuman. See Rabeinu Yonah on 32b dh shlosha that brings a machlokes and ultimately he says not like tosfos. See Shulchan aruch siman 193 sif 2 (mechaber) with taz sk 6 and Mishna Brura for further discussion of this point.
