Numbers, Units and Arithmetic: Course Description

The decimal system simplified arithmetic and is widely believed to be based on the number ten because humans have ten fingers. In this system, the location of the digit within the number is the determining factor as to whether it represents units, tens, hundreds, thousands, ten-thousands, one-hundred thousands and so-on. 'Numbers, Units, and Arithmetic' is a free course that examines this system that is based on powers of tens. It's provided courtesy of The Open University's Mathematics and Statistics Department. This course made up of three main topics of whole numbers, units of measurement and arithmetic. The subject of whole numbers covers number lines, decimals, place values and fractions. The units of measurement section focuses on how quantities are established, such as a 2-liter bottle or a foot-long hot dog. Unit of measure topics covered include unit conversions and measuring techniques. The final section on arithmetic examines arithmetic expressions using whole numbers, multiplication and division, decimal calculations, fractions and negative numbers. Students who complete the course will have the skills to perform a variety of tasks, such as writing whole numbers and comparing size, multiplying and dividing whole numbers and decimals and explaining arithmetic processes.
