Inequalities have greater than, less than, greater than or equal to, or less than or equal to signs. Equations have an equal sign.
Where instead of an equal sign, it might be greater than or less than signs.
greater than would be: > less than would be: < Equal would be: =
If there is an equal sign, it is called an equation; if there is a less-than, a less-than-or-equal, a greater-than, or a greater-than-or-equal sign, an inequality; if there is none of these, an expression.
"x3" is not an inequality. An inequality will have one of the following signs: less-than, less-than-or-equal, greater-than, greater-than-or-equal. for example: 3x - 5 < 15
You can use the Not function or the <> operator, which is the < and the > beside each other. To see if the values in A1 and A2 are not equal to each other, you can type: =A1<>A2 or =Not(A1=A2) In each case they will either give you TRUE if they are not equal or FALSE if they are equal, in the cell that you enter the formula into.
I assume you mean "inequality". An equation has an equal sign; an inequality has one of the inequality signs instead of an equal sign. These signs are: * Greater than * Greater than or equal * Less than * Less than or equal To solve an inequality, the main point to consider is that if you multiply or divide both sides by a negative number, you must invert the inequality sign. For example, if you multiply both sides by (-2), a greater-than sign would need to be changed to a less-than sign.
Less than < Greater than >
greater than is > less than is <
Greater than >Less than written on top of =.
Since there are no negative signs, and the expression is clearly not equal to zero, it's greater than zero.
If the first fraction is greater than the second, use > If the first fraction is less than the second, use < If the first fraction is equal to the second, use = Other possibilities include greater than or equal to and less than or equal to which are created by placing the greater than or less than signs on top of the equals sign.
