As students‚ we are taught the basics about mathematics. What the core properties of addition‚ subtraction‚ multiplication and division mean. How they work‚ and if we are lucky‚ we go into a little history of these methods. For those of us who have learned history‚ we learned that the basis for modern mathematics came from the Greeks and their writings. While this is correct‚ to truly understand the historical aspect of mathematics and its origins‚ one must study a time before the Greeks‚ when math

history of Mathematics. Ecs/13/01/0396 The area of study known as the history of mathematics is primarily an investigation into the origin of discoveries in mathematics and‚ to a lesser extent‚ an investigation into the mathematical methods and notation of the past. Before the modern age and the worldwide spread of knowledge‚ written examples of new mathematical developments have come to light only in a few locales. The most ancient mathematical texts available are Plimpton 322 (Babylonian mathematics

Value • What is the concept of place value? Place value means that the value of a digit in a number depends not only on its own natural value but also on its location in the number. It is used interchangeably with the term positional notation. • Place value tells us that the two 4s in the number 3474 have different values‚ that is‚ 400 and 4‚ respectively. A Review of the Decimal Number System • The word “decimal” comes from the Latin word decem‚ meaning ten

less tedious than viewing the data in binary representation. The binary‚ hexadecimal ‚ and octal number systems will be looked at in the following pages. The decimal number system that we are all familiar with is a positional number system. The actual number of symbols used in a positional number system depends on its base (also called the radix). The highest numerical symbol always has a value of one less than the base. The decimal number system has a base of 10‚ so the numeral with the highest value

Introduction In this essay I will be looking at the definition of place value and what does it mean‚ I will then explore the importance of the base-ten system in relation to place value and why knowing the base-ten system is important for understanding place value. I will then discuss the reason for why learners struggle with understanding the concept of place value‚ also I will discuss the importance of using concrete material. Finally I will look at the progression of levels from grade 2 into

An Introduction to Digital Logic Up until now the labs have dealt with electricity in its analog form where a quantity is described by the amount of voltage‚ or current‚ or charge... expressed as a real number. However a large proportion of electronic equipment‚ including computers‚ uses digital electronics where the quantities (usually voltage) are described by two states; on and off. These two states can also be represented by true and false‚ 1 and 0‚ and in most physical systems are represented
