In number theory, a happy number is a number which eventually reaches 1 when replaced by the sum of the square of each digit.
To find whether a given number is happy or not, calculate the square of each digit present in number and add it to a variable sum. If resulting sum is equal to 1 then, given number is a happy number.
It is 1729. Discovered by mathemagician Srinivas Ramanujan, 1729 is said to be the magic number because it is the sole number which can be expressed as the sum of the cubes of two different sets of numbers.
Happy Numbers is a relaxing, mind-blending, minimalist puzzle game that offer over 70 hand-crafted levels to immerse your self into. The game also constain a lot of beautiful characters to unlock.

Elementary Level: Children ages 8 to 12, or 4th through 6th grades. These children read sentences of approximately 10 words, with the maximum number of words being 20. Most books written at this level range between 20,000 and 40,000 words.
Middle school (also called junior high school)
Students attending middle school are around age 11 to 13. It starts with grade 6 and ends with grade 8. Middle school students usually switch from classroom to classroom. They may have different teachers in one school day.
Between 6-7 years your child may:
Be able to count up to 100 and count a few numbers backwards. Be able to do some basic maths such as adding '1 apple to 2 apples makes 3 apples' and will be able to tell when numbers are higher than other number.
To conclude: teach toddlers and preschoolers to count by actively bringing numbers into their lives. Children can learn to count at around age 2. Of course, some cases will always be different (either earlier or later). But to gauge a good age at which to start introducing numbers, you can start when they are toddlers.
Your 5-year-old now
Most 5-year-olds can recognize numbers up to ten and write them. Older 5-year-olds may be able to count to 100 and read numbers up to 20. A 5-year-old's knowledge of relative quantities is also advancing. If you ask whether six is more or less than three, your child will probably know the answer.
In Grade 1, students learn numbers to 120, build fluency with addition and subtraction within 40, explore comparing, and the concept of round numbers.
Play board games like Connect 4, Jenga, Snakes & Ladders, PLYT, or Dominoes. Or ask your child to design their own board game and dice. Play the game together and talk about the mathematical thinking, reasoning or problem-solving the game used.
Any power of 10 would fit that description, as all powers of 10 begin with a digit of one, followed by zeros. Therefore there are infinitely many happy numbers, as there are an infinitely many powers of 10.
There are infinitely many happy numbers. An intuitive proof for this is that there are infinitely many integers of the form 10n, which have one digit equal to one and some number of digits equal to zero.
Sophie Germain, a famous female mathematician, discovered that all numbers can be categorized as “happy” or “unhappy.” Let see how she came to her conclusion. A happy number is one in which the sum of each digit squared eventually ends in the number 1.
Lucky number 7 is even the basis for many myths and folklore. Ancient beliefs from around the world believed that the seventh son of the seventh son would be gifted with magical powers (both good and evil).
It is often interpreted to argue that the number of objects an average human can hold in short-term memory is 7 ± 2. This has occasionally been referred to as Miller's law.
The number seven is usually the overwhelming favorite. Why is that? In many cultures around the world, seven is considered a lucky number. This probably explains the affinity many people feel for the number seven.
