The negative numbers:
2 added to become one will still have a negative result - -
But the results will be positive if they multiply.
Fractions
The right pair of fractions could become whole if they combine.
But, multiplying will create numbers that are further from whole.
And what about a match between rationals and irrationals?
An irrational and rational combination, whether combining or multiplying, will never be rational.
At least they can console themselves with still being considered real. The imaginary number probably has a tougher time with finding love.
