Cardinals - nought, zero (in mathematics and for temperature) - nought, zero (in mathematics and for temperature) - 'oh' (in telephone numbers) - nil (in sports) - love (in tennis) – originates from the French word “l’oeuf”

Cardinals 100 - a/one hundred We offer a/one hundred different products. 'a' can only stand at the beginning of a number!!! 100 - a hundred / one hundred BUT: 2,100 - two thousand one hundred

Separation between hundreds and tens Hundreds and tens are separated by 'and' (in American English 'and' is not necessary). 110 one hundred and ten 1,250 one thousand two hundred and fifty 2,001 two thousand and one

We employ a thousand (one thousand) workers at present. Cardinals 1,000 a/one thousand We employ a thousand (one thousand) workers at present. (NOT: one thousand of) Note that a coma (,) separates the thousands from the other figures.

Cardinals 1,101 - one thousand one hundred and one 3,000 - three thousand (NO plural!!!) NOT: three thousands We have three thousand articles on display. (NOT: three thousands of articles)

Cardinals 4,356 four thousand three hundred and fifty-six 6,034 six thousand and thirty-four 5,204 five thousand two hundred and four

Cardinals Hundred, thousand and million take a plural –s: when the number is not precise after many: hundreds of customers thousands of enquiries many millions of dollars

With large numbers use commas as a separator!!! 57,458,302 45,342,001
