מָאתַיִם, אַלְפַּיִם
Yesterday we saw the Hebrew terms for three hundred and three thousand – שְׁלֹשׁ מְאוֹת 
listen and repeat and שְׁלֹשֶׁת אֲלָפִים listen and repeat, respectively.
listen and repeat and שְׁלֹשֶׁת אֲלָפִים listen and repeat, respectively.Higher multiples of those numbers follow a pattern:
and so on.
Going down to the multiple of two, however, we find a different phenomenon – a doubling of the word itself with an ah-yeem ending.
For example:
לֹא שָׁמַעְתִּי אֵיזֶה סְכוּם אָמַרְתָּ – מָאתַיִם אוֹ אַלְפַּיִם שְׁקָלִים?
I didn’t hear what amount you (a male) said – two hundred or two thousand shekels?
These words can describe both masculine and feminine nouns. For example:
בָּאוּלָם יוֹשְׁבִים מָאתַיִם גְּבָרִים וּמָאתַיִם נָשִׁים.
In the hall, two hundred men and two hundred women are seated.
The ah-yeem ending appears on many other words that come in pairs, such as עֵינַיִם listen and repeat – eyes, and מַגָּפַיִם listen and repeat – boots.
listen and repeat – eyes, and מַגָּפַיִם listen and repeat – boots.
