Question

It’s possible to do many simple tricks with numbers. Here is one trick, if you follow the instructions, you will find it’s really interesting.
First, write down your house number. For example, if your address is 73 Jin Shang Road, you would write down 73. After you write down your house address number, you double it. Then add 5 to this doubled number. For example, if your address is 73 and you double it, you will get 146. Then you add 5, you will get 151.
And then, multiply this number by 50. In our example here, you’ll get 7550. The next step is to add your age to this total. For example, if you’re 16 years old, you should add 16 to this total. In our example here, the result will be 7566.
After that, you have to add the number of days in a year, which is 365. In our example here, 365 added to 7566 is 7931.
The final step is this: Subtract 615 from the number that you have. Take away 615 from the total. In our example, 7931 minus 615 is 7316.
The result here—7316—is the trick. The first part of the number is the address and the last part of the number is the age of the person. That is, 73 is the address that we started with, and 16 is the age that we used.
Isn’t it interesting? Do you want to have a try now?
