One important difference between solving equations and solving inequalities is that when you multiply or divide by a negative number, then the direction of the inequality must be reversed, i.e. "less than" becomes "greater than", and "less than or equal to" becomes "greater than or equal to".
Actually, from a purist's sense, the reversal rule also applies with equations. Its just that the reversal of "equals" is still "equals". The same goes for "not equal to".

What is the difference between inequalities and equations using adding?
equations have an = sign, inequalities do not
What is the difference between inequalities and equations is true or false?
"What is the difference between inequalities and equations" is a question, not a statement. A question cannot be true or false. It can be pointless, or badly phrased or misguided but that is a different matter.
Explain in your own words the difference between compound inequalities with and and those with or?
An inequality with "and" is true if BOTH inequalities are true. Inequality with "or" is true if ONE of the inequalities are true.
What are some differences between equations and inequalities?
The main difference is that when solving inequalities, if you multiply or divide by a negative number you have to be careful, since you then also have to switch the sign (for example, change a "less-than" sign to a "greater-than" sign). If you multiply or divide by an expression that contains a variable, you have to consider the two cases: that such an expression might be positive, or that it might be negative.
What is the difference between a radical equation and a quadratic equation?
radical equations have sq roots, cube roots etc. Quadratic equations have x2.

What is the difference between equality and inequality?
equality does not change signs inequalities do for greater than or less than equations

An inequality with "and" is true if BOTH inequalities are true. Inequality with "or" is true if ONE of the inequalities are true.
What is the difference between algebra equations and expressions?
expressions don't have an equal sign and equations do

Solve the expression 3i 5-2i?
Expressions cannot be solved. Only equations or inequalities may be solved. Also, there is no symbol between 3i and 5.
What are the differences between solving equations and solving inequalities?
One important difference is that if you multiply or divide both sides by a negative number, you need to invert the inequality sign. Example: -2x > 5 Dividing both sides by (-2): x < -2.5 Note that the greater-than sign changed to a less-than sign, because of the multiplication by a negative number.
What is the difference between a linear quadratic and a quadratic quadratic?
There is no quadratic equation that is 'linear'. There are linear equations and quadratic equations. Linear equations are equations in which the degree of the variable is 1, and quadratic equations are those equations in which the degree of the variable is 2.
What is the difference between a dashed line and a solid line when graphing inequalities?
its different because they both repersent something.
Is there a difference between rational expressions and rational equations?
Yes. An equation has an "=" sign.
What in the difference between a numerical and algebraic expression?
Numerical equations have only numbers and symbols, while algebraic equations have variables also.
