Detailed Solution

Concept- Remember the strategy you must use to answer these problems, and also substitute a simpler number when necessary. For instance, if you must use the Vinculum approach to discover the table of 39, use (40 - 1) for 39.
We may write 46 = 40+6 to obtain the table of 46 using the Vinculum approach.
In the Vinculum approach, the number is multiplied by 40 and 6 instead of 46, and the result is then deducted.
Find the 46 multiplication table.
