Khorosho, davay obsudim vse eto, ladno? Problema, kotoruyu ya khochu zatronut, - eto ne tolko problema Chikago, eto problema profsoyuzov uchiteley povsyudu; nedostatochnoye finansirovaniye pensiy.

Ochevidno, znacheniye etogo chisla ravno 21, no yesli my poluchim eto zhe znacheniye s pomoshchyu formuly, my proverim formulu. Po formule 25-4 mozhno bylo by zapisat kak 5 ^ 2-2 ^ 2 i razlozhit na mnozhiteli kak (5 + 2) (5-2) = 7 (3) = 21. Takim obrazom, formula proverena. Znayte, kak oboznachat otvety po formule i chto oni oznachayut. Bud te konkretny pri chtenii formul. Poskol ku vse formuly ploshchadi nachinayutsya s A =, boleye polezno dobavit dopolnitelnuyu informatsiyu. V A = (pi) r ^ 2 luchshe vsego chitat eto tak: «Ploshchad kruga ravna pi, umnozhennomu na kvadrat radiusa kruga». Obyazatelno pomnite, chto ploshchad vsegda izmeryayetsya v kvadratnykh yedinitsakh.

Vychislitelnyye formuly trebuyut znachitelno bolshe usiliy dlya sozdaniya etogo znacheniya. My podrobno obsudim eto v № 3. Zapominayte formuly po mere ikh poyavleniya. Vy mozhete sdelat domashneye zadaniye, prosto vzglyanuv na formulu, no ne zhdite nochi pered ekzamenom, chtoby popytatsya zapomnit mnogiye formuly. Rabota s formulami po mere ikh postupleniya i nemedlennoye sokhraneniye ikh v dolgovremennoy pamyati garantiruyet, chto eta informatsiya budet usvoyena navsegda, a ne tolko dlya testa.
