Elementary math operations, addition,subtraction, multiplication and division. Displays results intabular form. Shows carries, borrows and crossouts.For elementary school students and their parents. This is NOT acalculator. Check your kids homework.NOTE:Add 0s after decimal point to increase precision of divisionresults5 / 2 = 2 remainder 15.0 / 2 = 2.5
