Do you know the difference between an expression and an equation?

An equation has a LEFT and a RIGHT side,
an algebraic equation will then look something like
These are all algebraic equations containing variables(p,r,z,st,n) are all variables here
Notice how they all have a left AND a right side,
An algebraic expression is however, terms of variables and constants multiplied or divided in a particular manner separated by '+' and '-'
each part of an expression between a '+' or a '-' is known as a TERM
Following drawing illustrates terms
There is no LEFT or RIGHT side in an expression, you may simplify and factor it, but you cannot solve it, it's merely a statement so to say
An algebraic INEQUALITY is pretty much the same as an EQUATION, but instead of the equal sign you may have the following signs
\[< \space \space ,\space \space > \space \space , \space \space \leq \space \space, \space \space \geq\]
If an inequality has the EITHER of the following TWO signs
\[< \space \space , \space \space >\]
It is known as a STRICT inequality
What do you think the answer is now??
When two expression are set to be equal, we say an equation has been established, any of the expressions may take either of the left or right side and the other expression will take the opposite side and an equation will be formed
