What is mathematics?

while searching for my class opener, read through this post <<what us mathematics education>>

when I was primary students, math is numbers;
when I was secondary studetns, math is solving different types problem using formula or steps given;
when I m in U, math is proving...

how about otherss?what they think about math? what do you think about math?

below is what I get from a blog

''If you look from the background mathematics education is

• psychology (deals with learning mathematics),
• sociology (deals with social issues in relation to mathematics), culture (deals with issues across the cultures in relation to mathematics teaching),
• history (deals with development of mathematical ideas across the history), and
• philosopy (deals with the issues of ontology, epistemology and axiology of mathematics teaching and learning).

At the foreground mathematics education is application of educational theories in teaching and learning mathematics.  ''

Haha, therefore we need to take Sejarah, falsafah dan Perkembangan Pendidikan Mathematik course now : )
