Because one side is the positive side (+) and one side is the negative side (-) They need to be there so people can place them in correctly. On objects there is also a plus and minus sign to match with the ones on the battery. You place the end with the plus sign in to match the end with the plus sign on the object and the end with the minus sign to match the minus sign on the object. Hope this helps!

How do you place 2 CR2016 batteries in a compartment Plus side on top of the other plus side Or plus side on top of other minus side?

If you put the two plus sides together, or the two minus sides together, then the total voltage of the battery is zero. They won't run anything, but they'll sure last a long time. They have to be stacked in such a way that if they were glued together to make a single package, then the package would have plus on one end and minus on the other end.


What is the square root of - 0.50?

there is no real square root of a minus number (think about it, minus x minus = plus, plus x plus=plus, and you can't have a minus x plus if it's a square root). However, there is an imaginary root which is "1/2i", where "i" represents the square root of -1. This number doesn't actually "exist" as such, it is just a theory which makes doing maths easier. However if you're not familiar with the concept of "i", you're probably not meant to end up with a minus square root (anything below A level further maths you don't usually need "i") . Check your calculations again.

Assuming you meant 7n (not just 7 at the end of your question) - first... simplify the equation. Numbers raised to powers get priority - so your new sum is... 5n - 64n + 25n + n + 7n.... This simplifies to... -26n
