The game this time only need our skills in basic arithmetic operations, such as add, subtract, multiply and divide. And very basic arithmetic operation that was to be used by us to know what is in the mind by others. Believe it or not, let us see for yourself!
Now, follow what I tell the following and you can also practice it later to friends, relatives, and those closest to you. Now I ask you to think of a number of what are dipikiran you. You may not think of any number, any or either up to you, free. Now multiply the number you think the two. Then the result is added to thirteen. After that the result subtract three. Then divide the result by two, and then subtract the number that you think of earlier. If your count is correct, surely the end result is the number five, right ?! My guess is not correct ?! : D. This does not mean I'm great, you can really do it.
The explanation Well, I do not know the numbers that you think before, then I suppose you think is the number x. Well, in mathematics something (in this context a number) that is not yet in the know value is often called by variables such as x, y, z, or in accordance with your wishes. First of all the numbers that you think before is x, then multiply it by two so that it becomes 2x. After that result in added to the thirteen that the result turned into 2x + 13. Then subtract three, then the result becomes 2x + 13-3 = 2x + 10. Then divide by 2, so it is obtained:
(2x + 10) / 2 = x + 5
Reduced the number who thought earlier, in this case the numbers in mind earlier is x, then the end result to be obtained are:
x + 5 – x = 5
So, regardless of the number that you had in mind by the end result is five. Simple and easy is not it?You can style it with a variety of games to add or create some new arithmetic operations, such that obtained special numbers such as the current date, birthday friend, and much more you can do.
