Peano Axioms Associativity of Addition
Associativity of Addition is one of the easy induction proofs. A short example is here. http://homepages.math.uic.edu/~libgober/math215/export/215problem.pdf Aitken lectures http://public.csusm.edu/aitken_html/m378/Ch1PeanoAxioms.pdf BYU lectures http://www.math.byu.edu/~andy/math190_Ch1.pdf The following skips associative but does discuss commutative and proof by induction. http://catdir.loc.gov/catdir/samples/cam031/82004206.pdf More difficult to read perhaps: … Continue reading
Giuseppe Peano 27 August 1858 – 20 April 1932
Peano was born today in 1858. Peano is best known for the Peano Axioms. The definition of addition by induction was invented by the school teachers Hermmann Grassmann in 1861. Richard Dedekind wrote his 1888 book that created New Math … Continue reading

Multiplication of Negative Numbers Recursive Continuation
Recently, the subject of how to teach or justify rules for multiplication of negative numbers has come out. The following is an approach based on the Peano Axioms. Natural numbers are 0, S(0), S(S(0))), … 1= 0′. S(0) = 1 … Continue reading

Peano Axioms Number Line
Peano Axioms for the Number Line. Think of a number line that starts at 0. It only has the natural numbers as ticks, so 0, 1, 2, etc. It has no fractions marked and it has no signs positive or … Continue reading
Pair of Number Lines and Successor Identities
This post concerns using a pair of number lines to illustrate the successor identities. At lower grade levels, we can simply use a pair of number lines to “prove” the successor identities. We actually make them plausible, but at an … Continue reading

Virginia Standards of Learning Math v Peano Axioms
The difficulty of the Peano Axioms is not greater either in abstraction or in formulas from algebra I. Natural numbers are defined by the Peano Axioms below. To give away the answer, they are 0,1,2,.. Note the natural numbers are … Continue reading

re: Alexandre Borovik Why is arithmetic difficult?
Math professor Alexandre Borovik has a post on understanding why arithmetic is difficult to learn. It is because it has a greater conceptual structure than is realized. He points out this complexity goes from hidden to explicit by use of … Continue reading
