By Larson; Hostetler
Designed for first-year developmental math scholars who desire aid in intermediate algebra, the Fourth variation of Intermediate Algebra owes its good fortune to the hallmark good points for which the Larson workforce is understood: studying through instance, available writing type, emphasis on visualization, and accomplished workout units. those pedagogical beneficial properties are conscientiously coordinated to make sure that scholars are higher in a position to make connections among mathematical options and comprehend the content material. the hot pupil help variation maintains the Larson culture of guided studying by means of incorporating a complete diversity of scholar good fortune fabrics in the course of the textual content. also, teachers and scholars alike can music growth with HM determine, a brand new on-line diagnostic overview and remediation instrument from Houghton Mifflin.
