This times table trick works with all answers up to 10 × 9. We think, “What do we now add to 8 to make 9?”Ĩ + 1 = 9 and so, the answer ends in a 1. We subtract 1 from 9 to find the tens digit of the answer.ĩ – 1 = 8 and so, the answer begins with a 8. We think, “What do we now add to 6 to make 9?”Ħ + 3 = 9 and so, the answer ends in a 3. We subtract 1 from 7 to find the tens digit of the answer.ħ – 1 = 6 and so, the answer begins with a 6. Here is another example of using the 9 times table trick with 7 × 9. We think, “What do we now add to 1 to make 9?” We subtract 1 from 2 to find the tens digit of the answer.Ģ – 1 = 1 and so, the answer begins with a 1. In general, we subtract 1 from the number and think what do we add to this answer to make 9?įor example, here is 2 × 9.

The units digit of the answer is the digit that you add to this tens digit to make the digits of the answer add up to 9.

Subtract one from this number to find the tens digit of your answer.

Look at the number you are mutliplying by 9.

There is a trick to learn the 9 times table up to 10 × 9: We can then see that all numbers in the 9 times table from 1 × 9 = 9 up to 10 × 9 = 90 all have digits that add up to make 9. Just remember the exception of 11 × 9 = 99, where there are still 9 tens. When teaching the 9 times table, we can easily write it out by starting with 0 tens and increasing them by 1 each time and also starting with 9 units and decreasing them by 1 each time. These units digits decrease by 1 each time until we get to 10 × 9 = 90, which has 0 units.Īfter this, we start at 9 again in the units column with 11 × 9 = 99, which decreases by 1 again in 12 × 9 = 108. The only exception is 11 × 9 = 99, where we repeat the 9 tens digit again.ġ × 9 = 9 starts with 9 in the units column and then we decrease this 9 by 1 to see that 2 × 9 ends in an 8. We can see in the 9 times table chart above that we start with 0 tens and increase the digit by 1 as we go down each row. The 11 × 9 = 99 times table is the only exception in which the tens digit does not change. We can also remember the 9 times table because the tens digits go up by 1 with each new times table and the units digits decrease by 1 with each new times table. The only exception is 11 × 9 = 99, which can be remembered because we simply repeat the digit 9. The numbers in the 9 times table up to 12 × 9 have digits that add up to make 9.

For these answers, we subtract one from the number we are multiplying by 9 to find the tens digit and the units digit is the number that we add to the tens digit to make a sum of 9. To learn the 9 times table, remember that we can use a times table trick to memorise the answers up to 10 × 9. The 9 times table is made by counting up in nines as shown:
