That statement is false. For example, (-2) - (-3) = 1 which is a positive number created from two negative numbers when subtracted.
The difference between any numbers is always positive.
It is always positive, and not just for decimal numbers but for all numbers.
Different whole numbers are always whole numbers, but I suspect you meant to ask about the difference between whole numbers. You can subtract two whole numbers and get a negative result. Whole numbers can't be negative.
No, it is not true.
The difference between a positive integer and a negative integer is ALWAYS positive.Suppose X and Y are positive so that -Y is negative,The the difference two numbers, A and B is A - B so the difference between X and (-Y) is X - (-Y) which equals X + Y. The sum of two positive numbers is always positive.
No. You can subtract two whole numbers and get a negative result. Whole numbers can't be negative.
If difference is taken to mean the first number minus the second then the answer can be positive or negative (or zero if the two numbers are the same). For example: the difference between -5 and -3 is -2 while the difference between -3 and -5 is +2.
Rates of deceleration are always expressed as negative numbers.
Yes, the product of three negative numbers is always a negative number.
