RULES Separation between hundreds and tens Hundreds and tens are usually 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 Hundreds Use 100 always with 'a' or 'one'. 100 - a hundred / one hundred 'a' can only stand at the beginning of a number. 100 - a hundred / one hundred 2,100 - two thousand, one hundred Thousands and Millions Use 1,000 and 1,000,000 always with 'a' or 'one'. 1,000 - a thousand / one thousand 201,000 - two hundred and one thousand Use commas as a separator 2,235,679 ď‚§

two million, two hundred and thirty-five thousand and six hundred and seventy-nine two million, two hundred thirty-five thousand, six hundred seventy-nine (amer.)

The Number 1,000,000,000 In English this number is a billion. This is very tricky for nations where 'a billion' has 12 zeros. 1,000,000,000,000 in English, however, is a trillion. But don't worry, these numbers are even a bit problematic for native speakers: for a long time the British 'billion' had 12 zeros (a number with 9 zeros was called 'a thousand million'). Now, however, also in British English 'a billion' has 9 zeros. But from time to time this number still causes confusion. Phone Numbers Each figure is said separately. 24 - two four The figure 'O' is called oh. 105 - one oh five Pause after groups of 3 or 4 figures (last group). 376 4705 - three seven six, four seven oh five If two successive figures are the same, in British English you would usually use the word double (in American English you would just say the figure twice) 376 4775 - BE: three seven six, four double seven five 376 4775 - AE: three seven six, four seven seven five
