Is there a relative reference and absolute reference excel video tutorials?

Users questions: Is there a relative reference and absolute reference excel video tutorials? Thank you pointers! ! The second video tutorial is too slow, the first can not be downloaded.
Experts answer: using the formula A1: is the relative ranks of reference, the formula to use $ A1: a line of relative references, absolute references to the formula used in column A $ 1: is a column relative references, line the absolute reference in the formula to use $ A $ 1: is the ranks of the absolute reference is the absolute reference to the cell's data, when inserting rows or columns, it will become $ A $ 2 or $ B $ 1, relatively little reference to the meaning of the absolute. So, how to ensure that the location of the absolute reference it? I NDIRECT ("A1"), you always maintain that position. As for what is quoted? Simple example: Suppose cell C1 has the formula: C1 = A1 + B1 C1 is the cell with the mouse hold down the bottom right corner of the small cross and to When the drop-down, C2 automatically generate the formula for the ranks of the reasons for A2 + B2 , The four cases mentioned above, in fact, filled by the formula by horizontal or vertical fill these two kinds of cases, the actual results only species.
