12×12 in genius mode. The product of 12 and 12 is 144.
This can be calculated by multiplying the two numbers together as follows:
12 × 12 = 120 + 24 = 144
In other words, we can think of 12 × 12 as the sum of 12 multiplied by 10 (which is 120) and 2 multiplied by 12 (which is 24).
Alternatively, we can use a multiplication table to find the product of 12 and 12. A multiplication table is a grid that shows the products of all pairs of numbers from 1 to 12 (or any other range of numbers). Here is the multiplication table for the numbers from 1 to 12:
| | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 | 10 | 11 | 12 | |---|---|---|---|---|---|---|---|---|---|---|---|----|----|----| | 1 | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 | 10 | 11 | 12 | | 2 | 2 | 4 | 6 | 8 | 10 | 12 | 14 | 16 | 18 | 20 | 22 | 24 | | 3 | 3 | 6 | 9 | 12 | 15 | 18 | 21 | 24 | 27 | 30 | 33 | 36 | | 4 | 4 | 8 | 12 | 16 | 20 | 24 | 28 | 32 | 36 | 40 | 44 | 48 | | 5 | 5 | 10 | 15 | 20 | 25 | 30 | 35 | 40 | 45 | 50 | 55 | 60 | | 6 | 6 | 12 | 18 | 24 | 30 | 36 | 42 | 48 | 54 | 60 | 66 | 72 | | 7 | 7 | 14 | 21 | 28 | 35 | 42 | 49 | 56 | 63 | 70 | 77 | 84 | | 8 | 8 | 16 | 24 | 32 | 40 | 48 | 56 | 64 | 72 | 80 | 88 | 96 | | 9 | 9 | 18 | 27 | 36 | 45 | 54 | 63 | 72 | 81 | 90 | 99 | 108 | | 10 | 10 | 20 | 30 | 40 | 50 | 60 | 70 | 80 | 90 | 100 | 110 | 120 | | 11 | 11 | 22 | 33 | 44 | 55 | 66 | 77 | 88 | 99 | 110 | 121 | 132 | | 12 | 12 | 24 | 36 | 48 | 60 | 72 | 84 | 96 | 108 | 120 | 132 | 144 |
As we can see from the table, the product of 12 and 12 is 144.
In summary, the product of 12 and 12 is 144, which can be calculated by multiplying the two numbers together or by using a multiplication table. The multiplication table shows the products of all pairs of numbers from 1 to 12, and we can find the product of 12 and 12 in the row for 12 and the column for 12.
