Explanation:

1. Ordering numbers in ascending way is ranking them from least to greatest.

The first number is the smallest, the next larger follows, and so the sequence continues until the last number, which will be the largest of the entire sequence:

2. The range function

The first cell in the range A2:B4 is A2 (column A, row 2).

The last cell in the rage A2:B4 is B4 (column B, row 2).

Then, the range comprises two columns (A and B) and three rows (2, 3, and 4).

That is a total of 2 × 3 = 6 cells. They are A2, B2, A3, B3, A4, and B4:

              A       B

      2     A2     B2

      3     A3     B3

      4     A4     B4

3. The range function with one column.

The first cell in the range A2:A10 is A2.

The last cell in the range A2:A10 is A10.

The column is the same for all the range. Only column A is in the range.

On the other hand, the range includes 9 rows: 2, 3, 4, 5, 6, 7, 8, 9, and 10.

Then, the number of cells is the product of the number of columns by the number of rows:

The cells are A2, A3, A4, A5, A6, A7, A8, A9, and A10.

Therefore, the range A2:A10 has 9 cells.

4. The function =COUNT identifies how many cells with are were in the range.

The format of the function is:

For example, =COUNT(A2:B4) shall count the number of cells in the range that contain data. If all the cells contain data, then the output shall be 9, but if, for instance, two cells are empty then the function shall return 7.

There are some variations of the function such as =COUNTBLANK(RANGE). This function returns the number of cells that are empty.

5. If you copy a formula

When you copy a formula in Excel or other worksheets, the references to cells are relative. Thus, the column and row references in the formula will change  in the same extent as the the cell that will contain the copied formula is away from the cell from which the formula comes from.

In this case, the formula that you are copying is in the cell D8 and you are copying it in the cell D9. That means that you moved 0 columns (keeping the column D) and 1 row down (moving from row 8 to row 9).

Then, when you paste the formula the references will be changed: 0 in the columns (same column) and the rows will increase in 1.

Therefore, A1 will be transformed into A2 (same column, 1 row more), and B2 will be transformed into B3 (same column, 1 row more).

In conclusion, the new formula in D9 is =A2+B3.
