Нужна ! complete the text using the correct passive form of one of the verbs below in each space. did nothing always exist or it (invent)? 'nothing' is zero or nought. it is a very useful idea and it (call) by many different names. in football, 0 (refer) to as 'nil'. so we say: "liverpool or (beat) two-nil (2-0) at home by manchester united." when you (give) marks in a test, you hope you will never get 'nought' out of ten or twenty. when we talk about the temperature, 'zero' (use). we say: "it is freezing today; the temperature has dropped to five below zero." the most unusual name for 0 must be that which (use) in tennis, 'love'; where the scoring goes 15-love, 30-love and so on. not many people realize that 0 did not always exist but is something that had to (invent). until the sixteenth century, the number system used in europe was the roman system, which (invent) about two thousand years ago. the roman system is not simple, for example the mark 'x' stands for ten and 'c' refers to a hundred. a much better number system (invent) by the hindus much earlier. the hindu system (bring) to europe in ad 900 by the arabs and sometimes (refer) to as the 'arabic system'. this system (build) on a base of ten and all numbers (write} with the digits; 1, 2, 3, 4, 5, 6, 7, 8, 9 and 0. so as all schoolchildren know, 10 means 'ten' and 40 means 'four times ten'.
