![]() Since this is less than 10, we would add a zero beforehand. That means that 3 and 0 are our first digits in the answer.įor the second part of the trick, it would be 9 (second digit in first number) multiplied by 1 (second digit in second number) = 9. In this case, you would add a zero before the answer.įor 59 multiplied by 51, it would be 5 (first digits in first number) multiplied by 6 (one digit higher) = 30. Now let's try one where the ones digits (the second digits, the ones that are supposed to equal 10) are multiplied together but don't exceed 10. Okay, so the above examples were all pretty easy. So 1, 5, and 6 are our first digits in the answer.įor the second part of the trick, it would be 2 (second digit in first number) multiplied by 8 (second digit in second number) = 16.ġ and 6 are the the last digits of the answer.ĭon't Miss: How to Find the Percent Given Two Numbers 59 x 51 = That means that 2 and 1 are the the last digits of the answer.įor 122 multiplied by 128, it would be 12 (first digits in first number) multiplied by 13 (one digit higher) = 156. That means that 1 and 2 are our first digits in the answer.įor the second part of the trick, it would be 7 (second digit in first number) multiplied by 3 (second digit in second number) = 21. 37 x 33 =įor 37 multiplied by 33, it would be 3 (first digit in first number) multiplied by 4 (one digit higher) = 12. Let's do a few more examples to hit this point home. ![]() If you look at the example above, the first digit in each number (24, 26) is 2, and the last digits in each (4, 6) equals 10.
