Because certain times tables always end in particular numbers.

The numbers in the 10 times tables always end with a 0 e.g 10, 20, 30...

The number in the 5 times tables always end with a 0 or 5 e.g. 5, 10, 15...

The 2, 4, 6, 8 times tables will always end in even numbers.

The 1 times table is obvious.

The 9 times table always has digits that sum to 9 e.g. 9, 18, 27...

The hardest times table is usually considered to be the 7 times table to learn as their is no obvious pattern to the numbers.
