One letter is required to express "I," four letters to say "love," and three letters to say "you." 143. "I adore you." Isn't it lovely? For some, 143 is simply a number. It was a present, a gesture of love, to **Mister Rogers** and the lovers on Minot's Ledge.

It is also the answer to **this puzzle**: What number comes after 1, 2, 4, 8, 16, 32, 64? The answer is 143.

There are 14 digits in the number 143. They are 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 0, 1, 2. The two zeros at **the beginning and end count** as one digit each. So there are seven spaces between the numbers, which means that there are seven different ways to divide the number by 10. The largest single factor of 14 is 7, so its prime factors are also 7. This means that there are exactly seven pairs of **consecutive numbers** below 1000 that can be divided by 14 without remainder. These are II, IV, VIII, XVI, XXIV, XXXVI, XIV.

Here are all the numbers from 1 to 1000 that can be divided by 14 with no remainder: I, II, IV, VIII, XVI, XXIV, XXXVI.

This has happened so frequently that Mister Rogers has grown to see that number as a gift, a fulfillment of destiny, since, as he puts it, "the number 143 symbolizes 'I love you.'" I love you. It takes one letter to say "I," four letters to express "love," and three letters to say "you." Add up the letters, and you get 143.

In mathematics, 143 is a highly repressed number. It is the smallest positive integer that cannot be expressed as **a single digit sum** of **its prime factors** (2 + 3 + 7 = 12). In other words, no matter how many times you add up the digits of 143, you will never reach 100.

Furthermore, there are two different ways of writing 143: either as 13 x 11 or as 1+43. If we write down all the numbers from 1 to 10 separately and then count back once, we get the result 13. So, 13 it is! And now let's try **another one**: write down all the integers from 0 to 9 and count forward ten times: the result is 43. Again, 13 and 43! These are the only two possibilities because if you add up the digits of any other number, at least one digit will always be more than 9. Therefore, this number isn't possible to write out as a single-digit sum.

In English, 145 equals one hundred forty-five words. This is a large number to write without using any symbols, such as letters, figures, or punctuation marks. Before computers, authors used to calculate the number of words in their books by writing them down by hand and then counting them. Today, computer programs are used for this task.

An author can use **many techniques** to make his or her writing sound more natural. One common technique is to break up long sentences with **shorter ones**. This can be done by inserting commas or short phrases called conjunctions. For example, instead of saying "I like apples, oranges, and pears," an author could write "I like apples, ORanges, and PEARS." By adding **these conjunctions** at appropriate places in her sentence, the writer could keep her ideas within the limit of one paragraph.

Another method used by authors to make their writing sound more appealing is through word choice. Words have different meanings and connotations. An author can choose words that have multiple meanings but don't imply anything negative when used together. For example, the word honest can mean truthful or fair.
