An annuity is a sequence of equal payments made at equal intervals of time. E.g. of annuities are weekly wages, monthly home mortgage payments, payments to a recurring deposit, quarterly stock dividend etc.
Simple Formulae and their Application
In the article Simple Formula and their Applications I we dealt with algebraic formulas in the second degree, i.e., formulas related to perfect squares and the sum and difference of two squares. In this article we will be covering the algebraic formulas in the third degree, i.e., formulas related to perfect cubes and the sum […]
Simple Equations in One Variable
When one expression is equal to another, the equality of these expressions may hold either for all values of the unknown variables involved or for some particular values of the variables involved. In the former case it is called an identity and in latter case it is called an equation.
Bills of Exchange
A bill of exchange is an instrument in writing, an unconditional order signed by the maker directing to pay a certain sum of money only to or to the order of a certain person or to the bearer of the instrument. The bill is written by the seller (creditor), called payee, to the purchaser (debtor), called drawee.
Algebraic Multiplication and Division
In the chapter Positive and Negative Quantities we explained algebraic addition and subtraction. In this chapter we shall cover simple algebraic multiplication and division.
Basic Number Properties – Commutative, Associative and Distributive
Basic number properties like commutative, associative, and the distributive properties are explored here. However, we can extend them to include the properties of zero and one. We also called these properties rules of arithmetic
Understanding Functions
If there exists a definite rule f which associates each element of x to a unique element y, then this rule f is called a real valued function and is denoted by f(x)
An Introduction to Fundamental Algebra
Algebra like Arithmetic is a science of numbers, with this distinction that the numbers in algebra are generally denoted by letters instead of figure. Hence whenever concrete quantities come under the domain of Algebra, it is only their measures with which we must concern ourselves.
Linear Inequalities
The mathematical statement which says that one quantity is not equal to another quantity is called inequation.
Integers
Integers often referred to as the positive and negative numbers. Integers are -4, -3, -2, -1, 0, 1, 2, 3, 4 and so on. All natural numbers, negatives of natural numbers and 0, together form the set of all integers.
