    Its not, is it?

    -4 - 4 = -8

    -4 / -4 = 1

    No?

    -4/-4 Firstly two negatives cancel out hence its 4/4 which is 1 therefore by mathematical induction it does not equal -8....

    You probably need to add brackets on your calculator

    0^0 = 1^0 = 1. Therefore 0 = 1.
    Hence -4/-4 = -4(1)/-4 = -4(0)/-4 = 0/-4 = 0 = 8*0 = 8*(-0) = 8*(-1) = -8

    So can I use these rules when dividing as well as multiplying?

    - - = +
    ++ = +
    - + = -
    + - = -

    is it? numberphile did a vid on that and said that it could be 0 or 1 or used to argue the situation or number which you need(which is generally 1)

    I thought it was undefined until this year and I'm a maths student lel. As far as I know it is generally accepted to be 1 but I can't recall why even though I have looked into it before.
