if you mean both dimensions are complex numbers, then you use foil. Example (1+i)(1+2i)= 1 + 3i - 2 (since i2 = -1) -1+3i that's a rectangle but you should understand if your in a class with complex #
Complex numbers are the square roots of negative numbers. i.e. root -1 = i
yes it does
electrical engineers and quantum mechanics use them.
Between Saran Wrap and foil, I would choose foil. But the best thing to use are freezer bags.
Yes, many
I suggest you read the Wikipedia article con complex numbers, specifically the section "Applications". One example is electrical engineering: in the case of AC, it helps to express all voltages, currents and impedances (equivalent of resistances) as complex numbers.
We should use it the same because it doesn't really affect our community
I'm not sure about how to use complex numbers to do this, but I've posted a link to a pretty neat website about Synthetic Division.
There are numerous applications; you should read the Wikipedia article on complex numbers for more examples. Some applications include: Get a better understanding of math. Even if you do calculations with real numbers, working with complex numbers often gives a greater understanding.Electricity, with AC, uses complex quantitites.Quantum physicsArt - ever seen the Mandelbrot set, or other fractals?There are numerous applications; you should read the Wikipedia article on complex numbers for more examples.

using contraction and expansion
Complex numbers can help visualize physical effects like the electromagnetic fields around wires carrying current. Refer to the link below.
