When is it difference of a positive and negative integer positive?
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.
Difference between natural number and integer?
natural numbers can not be negative. integers can be both positive and negative.
Is the difference of two negative integers always positive?
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.
Difference between positive and negative correlation?
If the two variables increase together and decrease together AND in a linear fashion, the correlation is positive. If one increases when the other decreases, again, in a linear fashion, the correlation is negative.
What is the difference between negative and positive plane in pcb design?
A positive plane is just like any other artwork layer - it shows where copper will be. A negative plane, like the name suggests, shows where there will not be copper.
