When you know your multiplication tables up to the 5 times table,
you can multiply most problems in your head. If you know your
2, 3, 4 and 5 times tables up to 10 times each number, then you
also know part of your 6, 7, 8 and 9 times tables. For the 6 times
table, you know 2 times 6, 3 times 6, 4 times 6, and 5 times 6. Th e
same applies to the 7, 8 and 9 times tables. As you learn your higher
tables, mental calculations become much easier. It is easy to learn
your 11 times table, and the 12 times table is not diffi cult. Six times
12 is 6 times 10 plus 6 times 2. Six times 10 is 60 and 6 times 2 is
- It is easy to add the answers for 6 times 12 to get 72.
Th e way tables used to be taught was diffi cult and boring. We have
seen how easy it is to learn your tables and how it can be done much
more quickly than in the olden days.
It is usual to learn tables up to the 12 times table. It is not hard to
learn the 13 times table if you know the 12 times table. If you know
12 threes are 36, just add another 3 to get 39. Twelve threes plus
