what is maths

In the US people shorten mathematics to math

In Australia we shorten it to maths 

Maths is mathematics. 

O, the anonymous user is from Australia!

No if it was a serious question it means he was not from Australia.  

Say what??

Australians call mathematics maths.  So an Australian knows what maths is.

You call mathematics math.   So some of your friends may not know that maths is the same thing. 

Oh! I now get it! Thank you!
