Table of 12

If we keenly observe the table of 12, we see that the digits in ‘unit digit’s place’ is always 2,4,6,8,0 and this order gets repeated respectively in the same manner.

As we know that multiplication is the repetitive process of addition, when we add the same number again and again, the number of times a number is added in itself, is the multiplication of that number. Suppose we add 12 in 12 four times, so it becomes 12+12+12+12, we can write it as 12×4. So, basically the value will be the same in both the cases, whether you add a number in itself or multiply it with the number to show how many times you wanted to add it, both are the same cases.

Let’s write the table of 12 – 

12×1 = 12

12×2 = 24

12×3 = 36

12×4 = 48

12×5 = 60

12×6 = 72

12×7 = 84

12×8 = 96

12×9 = 108

12×10 = 120

You can extend this table to 20 times or 30 times as per your requirement but at learning it up to 10 times is quite essential. You can also learn it up to 20 times for the safe side.

Trick to avoid error in the table of 12 – 

As you know that table of higher digits can cause confusion at times. Students often get confused by higher multiplications. To avoid this mistake, you can apply some simple techniques to avoid mistakes in the table of 12. 

If we keenly observe the table of 12, we see that the digits in ‘unit digit’s place’ is always 2,4,6,8,0 and this order gets repeated respectively in the same manner. So, if you suddenly start scratching your head to remember if 12×8 is 96 or 97, you can remember that the unit digit in the table of 12 cannot be 7, so you can eradicate your confusions easily in this way.

Examples for practice – 

Example – How to calculate 12×12 + 24×12?

Answer- We know that in the process of evaluation, we can always take the common terms outside to make the calculation easier. Here we can take 12 as common, so we get,

=12 (12+24) 

= 12 × 36

= 432 is our answer.

Example – What will be 12 times of 12 and 42 subtracted from it?

Answer- From the table, we can see that 12×12 will be 144. And if we subtract 42 from it, we get 144-42= 102 is our answer.
