FIGURES are made up of DIGITS (0, 1, 2, 3, 4, 5, 6, 7, 8, 9) and are usually easy to write, but can be tricky to say or write in WORDS.

In order to put FIGURES into WORDS, we must try to imagine that the number is in a PLACE VALUE table like this one.

How could we convert seventeen thousand and three? So our number is 17003 We put a space every 3 digits from the right, starting with the decimal point if there is one. 17 003 or 17,003 (remember, some people put a comma instead!)

32 Reading & writing numbers

Reading & writing numbers

Final skills Minus (-) sometimes comes before a number If there is a decimal point, we dont use tens, hundreds, thousands, etc to say the numbers after the point, we just list the digits E.g. 17.456 is seventeen point four five six, not Seventeen point four hundred and fifty-six
