What is the relationship between financial accounting and mathematics?

Accounting has close relationship with mathematics. The dual aspect concept, which is the basic concept of accounting, is expressed as a mathematical equation, known as accounting equation. Accounting computations such as computation of depreciation, determination of loan instalment, ascertaining of cash price in case of hire purchase and instalment systems requires use of mathematical techniques.
