# Problem 4.4 writing a division algorithm

Hogan Lovells Publications 27 September Exploring the contrasting views about antitrust and big data in the U. Using the calculator for division with remainder People often say that division is easily done on the calculator. Division with remainder, however, requires some common sense to sort out the answer. With a calculator using the division key: Then subtract 5 to get 0.

Calculator assistance may be extremely useful with larger numbers, but experience with long division is essential to interpret the calculator display This phenomenon is common to many similar situations in mathematics. When calculating a division, we are constantly calculating multiples of the divisor, and lack of fluency with multiplication is a significant handicap in this process.

The material in this module lays the foundation for multiplication, and then division, of fractions and decimals. Other applications of multiplication include percentages and consumer arithmetic. For example, we calculate the price of an item inclusive of GST by calculating 1.

A familiarity with multiplication and the expression of numbers as products of factors paves the way for one of the major theorems in mathematics. The Fundamental Theorem of Arithmetic states that every whole number bigger problem 4.4 writing a division algorithm 1 can be written as a product of prime numbers and such an expression is unique up to the order in which the factors are written.

The Fundamental Theorem of Arithmetic has far-reaching consequences and applications in computer science, coding, and public-key cryptography. Last, but not least, a strong grounding in arithmetic sets a student up for success in algebra.

The division algorithm uses multiplication and subtraction. As such, division demands that we synthesise a lot of prior knowledge.

This is what makes division challenging, and for many students it is their first taste of multi-layered processes. The ability to reflect on what you know, and implement it within a new, higher-level process is one of the generic mathematical skills that division helps to develop.

The implementation of the division algorithm is typically a multi- step process, and as such it helps to develop skills that are invaluable when students move on to algebra. The link to factors is also critical in later years. Just as the history of number is really all about the development of numerals, the history of multiplication and division is mainly the history of the processes people have used to perform calculations.

The development of the Hindu-Arabic place-value notation enabled the implementation of efficient algorithms for arithmetic and was probably the main reason for the popularity and fast adoption of the notation. The earliest recorded example of a division implemented algorithmically is a Sunzi division dating from AD in China.

Essentially the same process reappeared in the book of al Kwarizmi in AD and the modern-day equivalent is known as Galley division. It is, in essence, equivalent to modern-day long division. However, it is a wonderful example of how notation can make an enormous difference. Galley division is hard to follow and leaves the page a mess compared to the modern layout.

The layout of the long division algorithm varies between cultures. Throughout history there have been many different methods to solve problems involving multiplication.

Some of them are still in use in different parts of the world and are of interest to teachers and students as alternative strategies or because of the mathematical challenge involved in learning them. The method is very old and might have been the one widely adopted if it had not been difficult to print.

It appears to have first appeared in India, but soon appeared in works by the Chinese and by the Arabs. From the Arabs it found its way across to Italy and can be found many Italian manuscripts of the 14th and 15th centuries.

The digit 8 is placed in the bottom triangle and 0 in the top triangle. The digit 8 is placed in the bottom triangle and the digit 2 in the top triangle. The green diagonal contains the units. The blue diagonal contains the tens.

The orange diagonal contains the hundreds. The digits are now summed along each diagonal starting from the right and each result recorded as shown.Algorithms. When you write a general solution for a class of problems, as opposed to a specific solution to a single problem, you have written an algorithm.

We mentioned this word before but did not define it carefully. , subtraction with borrowing, and long division are all algorithms. One of the characteristics of algorithms is that. These days, however, it is not necessary to know a great deal about algorithms in order to apply optimization tools, especially when relying on the spreadsheet as a solution platform.

In that spirit, the book builds a library of templates against which new problems can be compared.

Discrete mathematics is fundamental to computer science, and interesting, challenging problems in discrete mathematics arise in programming languages, computer architecture, networking, distributed systems, database systems, artificial intelligence, theoretical computer science, and elsewhere. 🔥Citing and more!

In arithmetic, long division is a standard division algorithm suitable for dividing multidigit numbers that is simple enough to perform by hand. It breaks down a division problem into a series of easier steps. As in all division problems, one number, called the dividend, is divided by another, called the divisor, producing a result called the quotient.
