Hi I'm Kay and teach maths to primary age children. I have a special interest in children with maths learning difficulties and am currently looking into teaching and understanding children with dyscalculia:)
Hi Kay, I didn't know what that was, I had to look it up. Not to lessen the severity of those childrens suffering, I can say that math is really hard. I think we all have learning problems with it. At least I do. Math cost me a career in Biochemistry. For some reason I developed the integer disease. I thought that all problems had solutions like 1,2,3,4, 1/2, 1/3 and √2. The first time I saw scientific notation and decimals I freaked out. I couldn't grasp how some physical process could have an answer like 1.237653 of anything. Stymied me from that point on and I eventually grew to hate my favorite subject.
In mathematics, you don't understand things. You just get used to them.
Of course that result can be rigorously obtained, but who cares?
Combinatorics is Algebra and Algebra is Combinatorics.
