Algebra 7-9

Posobie Algebra 7-9, kak by prodolzhaya soderzhanie posobiya Matematika 5-6 (avtor Kh.Sh.Shikhaliev), vvodit chitatelya postepenno v predmet Algebra, soblyudaya tesnyy kontakt s posobiem Geometriya na ploskosti 5-9 (togo zhe avtora). V V klasse uchashchiesya znakomyatsya s mekhanizmom obrazovaniya mnozhestva deystvitel'nykh chisel, i zavershayut material etogo klassa razdelom Lineynaya funktsiya, gde rassmatrivaetsya reshenie sistem dvukh lineynykh uravneniy vsemi sposobami, v tom chisle matrichnym sposobom i s pomoshch'yu opredelitelya. V V klasse izuchayutsya algebraicheskie vyrazheniya i stepennye funktsii, vklyuchaya kvadratichnuyu funktsiyu i reshenie uravneniy i neravenstv vtoroy stepeni. V Kh klasse prokhodyat Pokazatel'nye i logarifmicheskie funktsii, Progressii i Kombinatorika. Vo vsey sisteme obucheniya matematike rabotayut elementy teorii mnozhestv i matematicheskoy logiki kak sredstva obucheniya, vklyuchaya i propedevtiku algebraicheskikh struktur.
