The product of three negative numbers is negative.
They will be negative numbers as for example -5+(-7) = -12
No, it is measured in positive numbers but it can be represented by negative numbers.
12
If the exponent is an even number you can drop the negative, because is you were to multiply it out the negatives would cancel out.

You can simplify fractions, sometimes, but you can never simplify whole numbers.
-3 + -12 = -15
Only integers (the whole numbers, including zero and negative whole numbers) are odd or even. Other numbers (like irrational numbers, fractions that don't simplify to integers, imaginary numbers, and so on) are neither odd nor even.
no you can only simplify ones such as 2 and 4 eiths
Logistics say you cant
-131.37 cannot be simplified.
-2
Simplify them.
You can't. A numeral is the simplest value you can get.
