# How can I love numbers

## Pay please! 143 and other significant numbers

On February 14 of all things the number 143 for "Pay, please!"? This is neither a typo, nor are we a month early to celebrate π-Day (3/14).

But then what could be exciting about the 143? She's not even prime. Okay, the 143 can at least be written as the sum of 7 consecutive prime numbers (11 + 13 + 17 + 19 + 23 + 29 + 31) and also plays a role in Waring's problem (A018886): Every natural number can be a sum of at most Write 143 powers of seven (by the way, 2175 is the smallest number that needs all 143 summands). But that's not the reason to look at the 143 today.

### Coded love message

In fact, on February 14th, it should be one of the most frequently typed numbers in chats, especially in the English-speaking world, because the individual digits stand for the number of letters in "I Love You"

To emphasize the statement, some also use 286, ie 2 × 143 = "I Love You, I Love You" or according to the same scheme 143637 ("I Love You Always And Forever"). The 831 (also 381) means the same as 143, but formulates it differently: "8 letters, 3 words, one meaning". Those who grew up with button cell phones like to type 459 into the chat window instead (see picture).

But now, no more emotionalism, we also have a heart for haters: "-143" negates the statement, so means "I Hate You" - just like 182: The 1 stands for an "I"; 82 uses the similarities between "Eight Two" and "Hate You".

### Internet slang: meaningful numbers
