4.5 is rational. Rational numbers are numbers that can be written as a fraction. Irrational numbers cannot be expressed as a fraction.
Signed numbers are "plus" and "minus" numbers.
There are no negative numbers in the Roman numeric system.
No.
Just put a minus sign in front of them. But be careful when subtracting numerals that have a subtractive element in them. For example: C-XL = LX because it is the same as 100 - (- 10 + 50) = 60. In mathematics a minus followed by a minus is equal to a plus - (- 10) = 10 try it out on your calculator.
40 would usually be written as XL (fifty minus ten)

Because both minus signs to be cut therefore minus * minus will be treated as plus numbers

It is also written as 10^100-1, since it is 9 followed by 99 nines, (A googol is 1 followed by 100 zeroes) it is a googol minus one.

Magnesium cation has a 2+ charge (Mg2+). The meaning is two electrons minus.
Anions are negatively charged ions formed by nonmetals gaining electrons. Nonmetals typically gain electrons to achieve a stable electron configuration, resulting in the formation of anions. Anions are commonly found in compounds involving nonmetals due to their tendency to gain electrons.
