A signed number is not blind if when it is divided into numbers with lower signs, their definite end product is not both + and - itself
a positive number can allways have a positive end product.
a negative number can be factored into numbers with lower signs and the end product can be both plus and minus, hence minus is blind
sqrt(-1) is like -1, blind.
Prove to me better that -1 is blind.
Prove to me also that all numbers except positive numbers are blind.
