Basic mathematics teaching and learning aid

摘要

A basic mathematics teaching and learning aid comprises of nine arrays of square spaces placed with powers of 10 from 10^−4 to 10⁶, numbers formed by repeated addition of some of those powers of ten, and other numbers. Dot and dash are in some of square spaces. Numbers, sign, arrows, mathematical symbols, percentages, equations and condition are in open spaces among the arrays. Formation, presentation and relations among these numbers, dots, dashes, sign, arrows, mathematical symbols, percentages, equations and condition are primarily used as an aid in teaching and learning fundamental areas of basic mathematics which mainly includes numbers in base-ten number system, addition, subtraction, multiplication, division, relations of a number of n with zero (number 0) in mathematical operations, whole numbers, fractions, and percentage.
