Abstract: A multiplication wheel is disclosed herein. One selects a number on a first wheel, selects a number on a second wheel and aligns a tab of yet a third wheel to that of the first wheel. The third and top wheel has a plurality of portals which are covered by numbers. One selects the cover with one of the numbers in the multiplication problem, leading to the product of the two selected and aligned numbers from the first and second wheel (one of which is redundantly uncovered on the top wheel) and thus finds the product situated beneath, showing through from the second wheel.

Abstract: A device and method of use for carrying out addition and/or subtraction problems is disclosed. The device has two circular dials rotatable with respect to one another. Each dial has at least one set of sequential numbers, and at least one selector allows for selection of a number on at least one of the dials. By rotating the circular dials in position, and selecting a number to be added or subtracted, one then is able to see correct mathematical equations around the entire circle.
