Good question I honestly don’t know I suppose it’s the temp but that doesn’t make sense
Cause
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!
It would be a minus sign. If the two signs are the same, the answer is positive. If the two signs are different, the answer is negative.

There is a number missing near the end: before " ... times plus 3".
Draw a circle more then half (75%), after that draw the minus sign on both sides of the end point of the circle. Note:- The end points of the circle must be on bottom side.
For the positive and negative charge that flow through the electrical charge
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.
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.

It makes a -2 from the answer you get in the end.
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
