different between ideal vs easy
ideal
English
Etymology
From French idéal, from Late Latin ide?lis (“existing in idea”), from Latin idea (“idea”); see idea.
In mathematics, the noun ring theory sense was first introduced by German mathematician Richard Dedekind in his 1871 edition of a text on number theory. The concept was quickly expanded to ring theory and later generalised to order theory. The set theory and Lie theory senses can be regarded as applications of the order theory sense.

Etymology
From Middle English eesy, esy, partly from Middle English ese (“ease”) + -y, equivalent to ease +? -y, and partly from Old French aisié (“eased, at ease, at leisure”), past participle of aisier (“to put at ease”), from aise (“empty space, elbow room, opportunity”), of uncertain origin. See ease. Merged with Middle English ethe, eathe (“easy”), from Old English ?eþe, from Proto-Germanic *auþuz, from Proto-Indo-European *aut- (“empty, lonely”). Compare also Old Saxon ?þi, Old High German ?di, Old Norse auðr, all meaning "easy, vacant, empty." More at ease, eath.
