Numerals can be divided into cardinals ordinals fractions

Numerals can be divided into: • • • cardinals ordinals fractions decimals frequency expressions

Cardinals 0 - 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

Cardinals 101 - one hundred and one 114 - one hundred and fourteen 124 - one hundred and twenty-four 241 - two hundred and forty-one (NOT *two hundreds and forty-one) (note the spelling of forty) - 300 - three hundred (NO plural!!!)

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 one

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 thirty-four 5, 204 five thousand two hundred and four

Cardinals • Hundred, thousand 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

Cardinals • 1, 000, 000 - a/one billion (milijarda) US$ 3, 456, 235, 444 three billion four hundred and fifty-six million two hundred and thirty-five thousand four hundred and forty-four American dollars EXCEPTIONS: YEN/YUAN (both plural and singular) • 1, 000, 000 - a/one trillion (bilion)
