**mathematics since around 30,000 BC**. - Ancient Greeks used little rocks to represent numbers. The name of
**Calculus**means**pebbles**in Greek. - The
**=**sign (“equals sign”) was invented by**16th Century**Welsh mathematician Robert Recorde, who was fed up with writing “is equal to” in his equations. - The word
**hundred**is derived from the word “hundrath”, which actually means**120**and not 100. **Zero**(0) is the only number which cannot be represented by**Roman numerals**.- Many Chinese hospitals do not have a 4th floor because the words
**four**in Japanese, Cantonese, Mandarin and Korean (shi, sei, si, sa) sound the same as the words in those languages for**death**. **Forty**is the only number with letters in alphabetical order, while**one**is the only one with letters in reverse order.- The number
**5**is pronounced as ‘**Ha**‘ in Thai language. 555 is also used by some as slang for ‘HaHaHa’. **Zero**is an**even**number. Mathematicians remember it. Many people take longer to decide whether it is even or odd.
