Practising mental arithmetic might seem like hard work, and to some people who find maths difficult it might even seem like a scary prospect. Mental arithmetic also helps to develop a real understanding of the mathematical methods of arithmetic, rather than just doing calculations through a process of memorization. People who need to use maths in their jobs, whether accountancy, retail or engineering for example, often do quite complex and fast estimations in their heads, so that they have a good idea of what the answer will be before they take the time to do a more complex calculation.
