    For real number the algebric structure will be only (R , +,×,-) . Division is not a binary operation on set of real number

  • @timepass-pd7iv
    @timepass-pd7iv 3 роки тому +18

    Division:
    20 ÷ 5 = 4;
    1.5 ÷ 3 = 0.5
    The division of nearly all real values will produce another real number. BUT, because division by zero is undefined (not a real number), the real numbers are NOT closed under division.

    BUT 3 ÷ 0 = undefined

    sir in the set of real numbers how does division satisfy the closure property ,what if I divide 7 by 0,both belong to real numbers but the result is undefined ,so the set is not closed. Shouldn't the set R* be closed wrt to division?

    7:27 Sir 5/0 is not a rational number because in rational number q is not equal to 0 acc to defination .

    • @sabihafirdous1345
      @sabihafirdous1345 2 роки тому

      Bt here sir said that Q*=set of all rational numbers excluding zero (0).
      Hence it proves that 0 is included in Rational numbers(Q).
      We can also write 0 in the form of p/q i.e 0/1=0.

      Division is not a binary operation in set R of all real numbers.
