PRACTICE PROBLEM 2.4 MULTIPLICATION TABLE SOLUTION
Create a multiplication table shown above using only 3 formulas & copying them. The table should
have a row of numbers from 1 to 10, a column of numbers from 1 to 10, and the cell where the row
and column intersect should contain the result of the two values multiplied together.
1. Write an Excel formula in Cell A4, which can be copied down the column into cells A5 through
A12, to create a list that increases by one in each successive cell.
=A3 + 1
Cell A4 comes right below the (given) value of ‘1’.
So to increment by one our math would be 1 + 1.
This allows us to copy the formula down the rows since each time it is copied down, the cell
reference row moves down by one – and thus the math remains correct.
2. In cell C2 write an Excel formula, which can be copied across the column into cells D2 through
K2, to create a list that increases by one in each successive cell.
=B2 + 1
Cell C2 comes right beside the (given) value of ‘1’.
So to increment by one our math would be 1 + 1.
Our Excel syntax would be
This allows us to copy the formula across the columns since each time it is copied across, the cell
reference column moves over by one – and thus the math remains correct.
3. Now create the values of the multiplication table assuming each cell in range B3:K12 is a product
of the corresponding value in column A for that row by the value in row 2 for that column.
Write the formula in cell B3 so that it can be automatically copied to complete the table through
cell K12.
=$A3 * B$2
We want all references to values in Column A to remain absolute according to column, but
relative according to row. When the formula is copied down, the row should change but when
copied across, the column should not change.
We also want all reference to values in Row 2 to remain absolute according to row, but relative
according to column. When the formula is copied across, the column should change but when
copied down, the row should not change.
