What have the Arabs ever done for us?
Arabs invented ideas in maths. They invented fractions. They also invented zero to show that there was nothing. Before Arabs, people left a space in the tens column to show there were no tens.
Our numbers (1,2, 3 and so on) look similar to Arabic numbers. Numbers are called ‘Arabic numerals’ because we learned how to write them from Arabs.
Arabs created windmills about 400 years before they were built in Europe.
