Why does minus and minus equal plus?

Because a minus changes the sign. If you take a plus and change it to a minus,you get a minus. If you take a minus and change it to a minus, it changes backinto a plus. Because you have only two options, minus and plus, here are all theoptions:+ & - = -+ & + = +- & + = -- & - = +===========================================Everything above the double line is a misleading, even dangerousdiscussion. When it's all over, both the questioner and the responderthink they have it all worked out, where in reality, it's all meaningless.The main problem is: Neither of them ever explains what ' and ' meansin the question, or what ' & ' means in the answer. Neither of those isa mathematical operation. The statement in the question, and the listof 4 'rules' in the answer, are correct for some mathematical operationsand either indeterminate or dead wrong for others.The question says: " ... minus and minus equal plus. "-- If ' and ' means multiplication or division, then it's a true statement.-- If ' and ' means subtraction, then it may or may not be true, dependingon the size of the two numbers.-- If ' and ' means addition, then it's always false.In the list of 4 items in the answer:-- If ' & ' means multiplication or division, then all 4 items are correct(but almost impossible to remember in this form).-- If ' & ' means addition, then items #1 and #3 are sometimes true andsometimes false, item #2 is always true, and item #4 is always false.-- If ' & ' means subtraction, then item #1 is always false, items #2 and #4are sometimes true and sometimes false, and item #3 is always true.


Why empty set is a proper subset of every set?

It isn't. The empty set is not a proper subset of the empty set.The empty set is a subset of every set, for the following reason. "A" is a subset of "B" means that if an item "x" is an element of "A", then it is also an element of "B".(x is element of A) implies (x is element of B)Since the empty set has no elements, the left part of the implication is false. Therefore, the entire implication is true. If you have trouble grasping this last part, look up the Wikipedia article, or other sources, for "trivially true" or "vacuous truth". (Briefly, an implication, like "F implies G", can only be false if "F" is true, and "G" is false - in all other cases, it is true.)


What is the simplest geometric shape?

The simplest geometric concept is an item that has no dimensions = a point. The next simplest is an item that has only one dimension = a straight line. The next simplest is an item that covers area but only needs one number to completely describe it . . . a circle.
