7, 22, 11, 34, 17, 52, 26, 13, 40, 20, 10, 5, 16, 8, 4, 2, 1 1 = 1 x 1, 1 + 3 = 4 = 2 x 2, 1 + 3 + 5 = 9 = 3 x 3 A=1, B=2, C=3… Think of a country that begins with your letter. Think of an animal that begins with the last letter of that country. You most likely chose to put a kangaroo in Denmark. 20% of 40 = 40% of 20 525600 + 6525 = 532125 532125 + 521235 = 1053360 1053360 + 633501 = 1686861 34 x 11 = 374 47 x 11 = 517 23 x 9 = 230 – 23 = 207 For 03600029145 you should calculate something like this: 5+4+1+9+2+0+0+0+6+3+0+ 5+1+2+0+6+0+ 5+1+2+0+6+0 = 58 10 – 8 = 2 The extra digit would be 2! Find the digital roots of the first number: 2+8+7+8 = 25 2+5 = 7 Do the same for the second and third numbers. We’ll spare you the time and tell you that they are both 6. So, take 7×6 (the digital roots of the two numbers you are multiplying) which equals 42. 4+2 = 6. Since 6 = 6 the math is right! 14 15 16 21 22 23 28 29 30 No matter what square he chooses you can quickly tell him what they all add up to. Just multiply the middle number by 9! 22 x 9 = 198 Suppose you’re on a game show, and you’re given the choice of three doors: Behind one door is a car; behind the others, goats. You pick a door, say No. 1, and the host, who knows what’s behind the doors, opens another door, say No. 3, which has a goat. He then says to you, “Do you want to pick door No. 2?” Is it to your advantage to switch your choice? The answer is incredibly that yes, your chances increase if you switch doors. You’ll have to google it to find all the proofs but a quick way to visualize it is to imagine not 3 doors but 1 million doors. You choose 1 door and then the game show host opens all but 1 other door. This time the answer becomes more obvious. You should definitely switch. Would your really trust yourself to have picked the right door out of 1 million? Here is another intuitive explanation offered by Matthew Carlton: An intuitive explanation is that if the contestant picks a goat (2 of 3 doors) the contestant will win the car by switching as the other goat can no longer be picked, while if the contestant picks the car (1 of 3 doors) the contestant will not win the car by switching.
