In this video, I’ll show you a cool trick
that you can do on calculator to show off. That’s comin up. Ok, let me show you the trick first, what
it looks like. Let’s say I ask from you, which number you
like, from one to nine. Give me any number from one to nine. Let’s say you say seven. Then I’ll tell you to punch sixty three, six
and three, and equal to sign. Now, you got all your sevens. This is the digit that you like. Let’s do it one more time. Let’s say, I ask you which digit you like. Which number from one to nine. And you say, I like four. And I tell you to punch thirty six and equal
to sign. And you get all fours on the screen. Ok, let’s learn how to do it. First, not showing the other person, your
spectator should not see this thing. You should, just this is the preparation before
the trick. Just punch in one, two, three, four, five,
six, seven, and nine. From one to nine except eight. After that, multiply by zero. And now, the calculator looks like it’s just
starting, nothing has been punched before. So, just, if the other person says five, just
in your mind multiply five by nine, and it will be forty five. He has to or she has to punch forty five. As I, as we did with seven, I told you to
punch sixty three, because nine times seven is sixty three. If it’s four, nine times four is thirty six. So, we have to punch thirty six. Let’s say, the other person says, I like five. So, nine times five is forty five. You have to tell him that, punch forty five,
and equal to sign. It will all be fives. Ok, let’s see you in the next video.
