Angel Number 421

   Step 1 

                Select any whole number.

   Step 2 

                If it is an even number, divide by 2; if it is odd number multiply by 3 and add 1.

   Step 3 

                Repeat the process mentioned in step 2 until you get the loop value 4, 2, 1 in

                repetition.

Example

  Whole number is 15.

  15 is an odd no; so (15 × 3) + 1 = 46

  46 is an even no; so 46 / 2 = 23

  23 is an odd no; so (23 × 3) + 1 = 70

  70 is an even no; so 70 / 2 = 35

  35 is an odd no; so (35 × 3) + 1 = 106

  106 is an even no; so 106 / 2 = 53

  53 is an odd no; so (53 × 3) + 1 = 160

  160 is an even no; so 160 / 2 = 80

  80 is an even no; so 80 / 2 = 40

  40 is an even no; so 40 / 2 = 20

  20 is an even no; so 20 / 2 = 10

  10 is an even no; so 10 / 2 = 5

  5 is an odd no; so (5 × 3) + 1 = 16

  16 is an even no; so 16 / 2 = 8

  8 is an even no; so 8 / 2 = 4

  4 is an even no; so 4 / 2 = 2

  2 is an even no; so 2 / 2 = 1

  1 is an odd no; so (1 × 3) + 1 = 4

  4 is an even no; so 4 / 2 = 2

  2 is an even no; so 2 / 2 = 1

  So the loop 4..2..1 goes on and on.

Tip : The angel number 421 is the smallest prime formed by the two powers in logical order from right to left.

Why should I learn math?

Have you ever asked this to yourself when you were a kid? Well, I know many kids who ask this to their parents and teachers. They are unable to find the importance of math. Sometimes, I too think that why I learnt so many theorems in math, when I actually don’t use them.  

In a country like India, math is considered as a very important subject. If you are not good at math, then you are not considered intelligent enough. Almost all the competitive exams have a math section. It is believed that rigorous math education is critical in creating the jobs that drive an economy. Almost all the fields use the concepts of math in one or another form. Math is also a part of our day to day life. One should be aware of math concepts to find out solution to certain problems in real life. 

It is difficult to answer certain questions which we face in our daily life without the knowledge of math. For example, 250 gms of tomatoes are required for 1 kg chicken, then how much tomatoes will be required for 750 gms. of chicken. Well, if someone doesn’t know basics of math, then this problem will seem like herculean task.  Cooking is a technique which uses basic concepts of math to maintain precision and quality. Ingredients are carefully measured and added into the dish to maintain the uniformity and taste of the dish. We use the concepts of measurement in the cooking. And not only cooking, but many other daily activities need math concepts.

My grandmother is illiterate. Once she went to bank and asked some guy’s help to withdraw Rs. 10,000. When she came back home, she had only Rs. 5500. Since, she didn’t know how to count money, she trusted that guy to count and give her. Well, her lack of education did cost us some amount but it made us realize that how important it is to survive in today’s world. If you don’t know your numbers then it is very difficult to keep a track of your money as it is nothing but a game of numbers.

Hence, it can be said that it is very important to learn math. It is not only a subject but a necessity of life.

Math Trivia :)

·         The implicit curve equation (x2+y2-1)3-x2y3=0 produces the heart shape.

·         The term Googol (10 followed by 100 zeros) was invented by a 9-year old boy Milton Sirotta.

·          

·         1089 multiplied by 9 gives an exact reverse: 9801.

·         From 0 to 1000, the letter "A" only appears in 1000 ("one thousand").

·         2 is called the "oddest" Even-Prime number. 2 is a unique Even-Prime because while all Evens are divisible by 2, any number apart from 2 that is divisible by 2, is not a Prime.

·         40 when written "forty" is the only number with letters in alphabetical order, while "one" is the only one with letters in reverse order.

·         A dollar can be made into small change in 293 ways.

·         If you add up the numbers 1-100 consecutively (1+2+3+4+5...) the total is 5050.

·         2 and 5 are the only prime numbers that end in 2 or 5.

·         The largest known prime number (so far) is 12,978,189 digits long.

·         The digits to the right of the Pi's (3.141...) decimal point can keep going forever, and there is no pattern to these digits at all.
