INSTANT MULTIPLICATION
Multiply 54 × 11
Since 5 + 4 = 9, your answer is simply
594
What about 82 × 11?
Here, since 8 + 2 = 10, the answer is NOT 8102!
As before, the 0 goes in between the numbers, but the 1 needs to be added to the 8 to get the correct answer:
902
NB: if the two numbers are added and the result produces a number less than 10, then the result is put between the two numbers. However, if the two numbers added together produces a number equal to ten or above, then the second digit goes in between the numbers, but the first digit is added to the first digit of the three, and there is your answer.
For example, multiply 86 × 11
Although, 8 + 6 = 14, the answer is not 8146!
As before, the 4 goes in between the numbers, but the 1 is added to 8 to get the correct answer:
946
