all cells in the B column of any worksheet in this workbook
It seems each worksheet covers total expenses for each month, and hence workbook must have 12 such with one month for each worksheet. Also, the 3D range is a special option in Excel to reference all cells or a selected group of cells for all the worksheets. However, it should be all B cells as B2: B4 apart from this, others in B column also has expenses. And hence, the above option is the correct one.
Meteoroid: A small part of a comet or asteroid that orbits the Sun.
Meteor: the light occurrences resulting from a meteoroid entering and vaporizing the Earth's atmosphere; for example a shooting star.
Meteorite: A meteoroid that completes its journey through the atmosphere of the Earth and lands on the surface of the Earth.
So, When the chunk of iron was flying in spaces and attracted by the Earth's gravity is called Meteoroid.
When it entered the atmosphere burning brightly it is called Meteor.
The solid part that lands on the ground is called Meteorite.
Whole, integer, rational, real
The answer is 6i, where i is the square root of -1.
This can be checked by the standard formula for two complex numbers:
(a,b)x(c,d) = (ac-bd, ad+bc)
(0,6) x (0,6) = (0x0 - 6x6, 0x6 + 6x0) = (-36, 0) or just -36
answer is 144
