Question

Is there such a thing as 0x, there's 5x, 6x, 19x, x etc., but 0x... just sound weird to me.

Answer 1

Zero × anything is zero, so no... you'll never see 0x. If for some reason you do, just rewrite the equation without it... because it's zero. :)

Answer 2

We write 0 in place of 0x.

Explanation:

• When we multiply any number, any variable, any expression, any equation with zero the result is always zero.
• 
  `0* x = 0`
• So, when we multiply 0 by x and write it as 0x, it makes no sense because ultimately the answer is zero.
• So, usually in practice we do not use such thing as 0x.
• We directly write zero(0), in place for 0x.
• So, 0x is not used in general practice, where as we can use the term 5x, 4x, 3x, 2x and so on.
• There is no such thing as 0x.
