    Hi there. I was having a real problem finding out is zero was a cardinal number or not?
    This website says it is...

    https://www.yourdictionary.com/cardinal-number

    and this website says it is not?

    https://byjus.com/maths/cardinal-numbers/

    In fact the issue seems to be very unclear.

    Zero is not in the ordinal set as there is no ZEROth step. Is that right?

    I want to know is I am standing at zero, and a Take a step, Do I count the zero number, and is this a cardinal number?

    I apologise if this seems like a very simple maths question. Thanks in advance for your help..
