Physical Significance of Multiplication

[Curious555]

Hi,

The multiplication sign in p = m x v means that mass 'm' moves with velocity v.

But...

The multiplication sign in E = m x c^{2 does not mean that mass 'm' moves with speed C.}

^{I find it surprising. Can anyone help me quench my surprise and if possible give some more examples where 'multiplication' has such different meanings, with the terms in the equation being mass and speed/velocity.}
