we have studied that reducing sugars are monosaccharides BUT above maltose and lactose are disaccharides still we are calling them as reducing sugar.WHY?

Reducing sugar are those which reduces Cu+2 to Cu+1. Unlike most other disaccharides, sucrose is not a reducing sugar and does not exhibit mutarotation. Because in sugar there is no glycosidic linkage between glucose and fructose so that they can hydrolyze and reduce fehling solution.
Maltose obtained by enzyme-catalyzed hydrolysis, consists of two D-glucopyranoses joined by a 1,4'-beta-glycoside bond. Thus maltose is a reducing sugars because the anomeric carbons on the right-hand sugar are part of a hemiacetal.
Lactose is a reducing sugar. It exhibits muta-rotation and is a 1,4'-beta-linked glycoside. Acidic hydrolysis of lactose yields 1 equiv of D-glucose and 1 equiv of D-galactose
