| +[22] | + | + | + | |
| 0 | 0 | 0 | 0 | |
| 0 | 0 | 9 | 0 | |
| 5 | 7 | 8 | 0 | |
We may now combine these symbols in a variety of ways, so as to form any required function or functions of them, and we may then inscribe each such function below brackets, every bracket uniting together those quantities (and those only) which enter into the function inscribed below it. We must also, when we have decided on the particular function whose numerical value we desire to calculate, assign another column to the right-hand for receiving the results, and must inscribe the function in the square below this column. In the above instance we might have any one of the following functions:—
Let us select the first. It would stand as follows, previous to calculation;—
 |  |  |  |  |
| + | + | + | + | |
| 0 | 0 | 0 | 0 | |
| 0 | 0 | 0 | 0 | |
| 0 | 0 | 9 | 0 | |
| 5 | 7 | 8 | 0 | |

The data being given, we must now put into the engine the cards proper for directing the operations in the case of the particular function chosen. These operations would in this instance be,—
Firstly, six multiplications in order to get
