    What do you mean you can not divide a meter without estimations or irrational numbers? Do you mean fractions or decimal? 1m/3=3.33… dm ( repeating, which means it is a rational fraction)

      Anyone who thinks you can divide one number by another and get an irrational number… doesn’t know what irrational means.

        Irrational numbers are ones with the square root of negative 1 as a factor, right?

          irrational numbers are numbers which are not a ratio of integers

          complex numbers, often called “imaginary” numbers, are ones with components of unit i =√-1

            complex numbers, often called “imaginary” numbers,

            Aside: mostly, but complex numbers are an addition of both a real number and an imaginary number: a + bi. It just happens that a can be 0, making it a strictly irrational number when b ≠ 0.

            Thus, the imaginary numbers are a strict subset of the complex numbers.
