Linear Inequations
A statement is an assertion or a sentence that is either true or false, but not both. A variable is a symbol that may represent any member of a specified set called replacement set or domain of that variable. A mathematical expression is a symbolic..

A real number line can be used to represent the solution set of an inequation (Linear). The convention is that O (a hollow circle) marks the end of a range with a strict inequality (i.e. < or >) and (a darkened circle) marks the end of a range involving equality as well as inequa..

In a given sentence, the variables are replaced by letters and the different operations are replaced by their mathematical symbols. We now arrive at a formula. In a given sentence, the variables are replaced by letters and the different operations are replaced by their mathematical ..
Summary of Simultaneous Equations
Summary Simultaneous Equations - Finding the solution by the method of substitution. Finding the solution by the method of substitution. (i) Coefficients of one of the variables (say x) in the two equations are made equal, by multiplying them with suitable factors. (ii) By addition or subtraction, ..
Symmetric Functions
Any expression f( a , b ) involving two numbers a and b is said to be symmetric if it remains unchanged when a and b are interchanged. [i.e. if f( a , b ) = f( b , a )]. Some of the symmetric functions of a and b are All symmetric functions of a and b can be expressed ..

Normally propositions are joined by 'OR', 'AND', 'NOT', 'IF .. THEN..' and 'IF AND ONLY IF' called the logical connectives . They are symbolised as follows: If two or more statements are combined by the use of words like 'AND', 'OR', 'IF AND ONLY IF ', then the resulting statement is called a ..

Application to Switching Circuits - The application of Boolean algebra to electronic devices such as computers, lies in the restriction of the variable to two possible condition 'On and Off' or 'True or False' or numerically '1 or 0'. The electric circuits carry out the Boolean logic. In ..
The Biconditional statement
If two simple statements p and q are connected by the connective 'if and only if', then the resulting compound statement is called the biconditional statement. Symbolically it is represented by p q. Example: An integer is even if and only if it is divisible by 2. It is a biconditional ..

This tutor was excellent. very clear on all of the problems. I would like to have more tutoring from Tutor Vista
This Tutor Vista is GREAT! loved this session, it helped me heaps.
Terific helped showed how to apply formulas i will study these examples to go further--much gratitude--will come back again ThankYou
all my questions were answered in a very clear way and i learned a new math rules which i did not know this service is very helpful - mike
Looking for More Help!
