A method of teaching mathematical operations is disclosed. The method includes employing a new numerical notation system. The numerical notation system is comprised of a vertical line (staff) and a plurality of points along the vertical line. The points along the vertical represent a numerical value, and any point along the vertical line has a value equal to two times the value of the immediately preceding point. One point along the vertical line is designated as the unity point, which is the point at which whole integers begin. The unity point has a numerical value of one (1). Points above the unity point represent fractional values. The numerical notation system indicates or represents a number value by one or more perpendicular lines (flags) extending to the right or left of the vertical line represent negative values. A number value is represented in the notation system by the sum of the value of the perpendicular lines extending from the points along the vertical line. The method, which employs the numerical notation system, is useful for, among other things, teaching the nature and features of mathematical operations and helping people understand multi-base arithmetic. The numerical notational system may be useful to teach mathematical concepts to children and adults who have math learning disabilities.
