Mathelogic: August 2008

Thursday, August 14, 2008. Decimal or Base Ten or Denary Numeral System. Decimal is a base (or radix) 10 numeral system. Meaning, the system has ten symbols or numerals to represent any quantity. These symbols are called Digits. The Hindu-Arabic numeric system and Chinese counting rods system are the two systems that required no more than ten symbols. Decimal numeral system is the most commonly used numeral system perhaps because humans have ten digits over both hands. So 17591 can be expanded as 1x10.

Mathelogic: Infix, Prefix and Postfix
http://mathsexplained.blogspot.com/2008/09/infix-prefix-and-postfix.html
Sunday, September 14, 2008. Infix, Prefix and Postfix. An operator is a function that specify specific actions on objects. Those objects which acts as an input to the operator is called an operand. For eg., in 3 5 , the symbol " " is a addition function (operator) which operates on the operands "3" and "5" to produce the result 8. Depending on where we place this operator and the operands, we have three different notations. For eg., let us take 2 6 / 8. Here / operates on "the result of 3 5" and 8. T...

Sunday, October 25, 2009. Properties of Addition, Subtraction. Properties of Addition :. The following are the properties for addition. Commutative property : It says that we can change the order of numbers (operand). Given a expression where we have multiple additions (say A B C D, where A,B,C,D are numbers), commutative property says that we can place the numbers A,B,C,D wherever we want in that expression. Something like this B C A D. In short, (A B)=(B A). Properties of subtraction :. The following a...

Mathelogic: October 2008
http://mathsexplained.blogspot.com/2008_10_01_archive.html
Sunday, October 12, 2008. Order of Operations - BODMAS. As said here in this. 1) B or P - Brackets or Parenthesis. 2) O or E or I - Orders or Exponents or Indices (square roots, powers, radix etc.). 3) D - Division. 3) M - Multiplication. 4) A - Addition. 4) S - Subtraction. Let us have an example. (3 * (5. 5) ) /5 (3*15)/5. We have an exponent. 5. 25 We don't have division. Then we have multiplication. 3* 25 = 75. Then we have addition 75 5=80. Now that the first bracket is evaluated....3 (5*4) , the...
