Nucleus minus two protons and minus two neutrons (alpha particles are 4He nucleii)
its pre beta minus
it equals 5
For each unit sold, a rough approximation isProfit = Selling price minus Cost of production.It is an approximation because it does not take account of taxes, inventories and so on.
False
The answer is "FALSE".
True
probably false, because MINUS one. It might have one less in it's outer shell
the answer of negative 4 minus positive 21 is positive 25 because you leave the negative 4 as is, change the minus to a plus, and change positive 21 to negative 21. (Leave Change Change)
false
GPP (gross primary production) minus cellular respiration.
FALSE!
If you mean the ADDITIVE INVERSE, change the minus sign to a plus sign. (And if you see a plus sign, you change it to a minus sign.)
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.
