![]() How to Remember Greater Than and Less Than Signs Now we'll finally get to talk about why all these photos are of crocodiles. Greater than or equal to-the number on the left is greater than or equal to the number on the right 2 or 3 ≥ 2ĭoes not equal-the number on the left does not equal the number on the right 2 ≠ 3 Less than or equal to-the number on the left is less than or equal to the number on the right 2 or 3 ≤ 3 Greater than-the number on the left is greater than the number on the right 3 > 2 We’re all familiar with the equal sign, “=” at this point in math. Hence the name “inequality” means that two things are not equal. Inequalities are math problems that don’t resolve with a clear “equals” answer-instead, they compare two things, demonstrating the relationship between them rather than showing that one is equal to another. What Are Greater Than and Less Than Signs For? Not knowing what the signs mean may make your math homework feel something like this. #Does not equal sign stata how to#In this article, we’ll be talking about what inequalities are, how they’re represented, and how to remember which sign means what. But these symbols are very useful, because they help us show the relationship between numbers or equations in a way that doesn't just say that they're equal. If you were to change the formula to =NOT(B2>A5) it would return TRUE and the cell would be formatted.What do those little sideways carat symbols mean? They're inequalities! Inequalities can be difficult to get a handle on, especially because the greater than and less than signs look so similar. In this case A5 is greater than B2, so the result will return FALSE. If A5 is NOT greater than B2, format the cell, otherwise do nothing. If A2 is greater than B2, format the cell, otherwise do nothing. Using the earlier Dates example, here is what the formulas would be. Next, select the “ Use a formula to determine which cells to format” option, enter your formula and apply the format of your choice. When you do this you can omit the IF function and use AND, OR and NOT on their own.įrom the Home tab, click Conditional Formatting > New Rule. You can also use AND, OR and NOT to set Conditional Formatting criteria with the formula option. Using AND, OR and NOT with Conditional Formatting In this case, A5 is greater than B2, so the formula returns FALSE. IF A5 is not greater than B2, then return TRUE, otherwise return FALSE. 03/12/14 is greater than 01/01/14, so the formula returns TRUE. IF A2 is greater than B2, return TRUE, otherwise return FALSE. Here are some examples of using AND, OR and NOT to evaluate dates. You can also substitute Text or Numeric values for the TRUE/FALSE values to be returned in the examples. The remaining True/False arguments are then left as part of the outer IF statement. Note that all of the examples have a closing parenthesis after their respective conditions are entered. IF A7 (“Blue”) is NOT equal to “Red”, then return TRUE, otherwise return FALSE. In this case 25 is not greater than 50, so the formula returns TRUE. IF A6 (25) is NOT greater than 50, then return TRUE, otherwise return FALSE. Here are the formulas spelled out according to their logic: The NOT function only takes one condition. The AND and OR functions can support up to 255 individual conditions, but it’s not good practice to use more than a few because complex, nested formulas can get very difficult to build, test and maintain. NOT – =IF(NOT(Something is True), Value if True, Value if False)įollowing are examples of some common nested IF(AND()), IF(OR()) and IF(NOT()) statements. OR – =IF(OR(Something is True, Something else is True), Value if True, Value if False) When you combine each one of them with an IF statement, they read like this:ĪND – =IF(AND(Something is True, Something else is True), Value if True, Value if False) Here are overviews of how to structure AND, OR and NOT functions individually. The value that you want returned if the result of logical_test is FALSE. The value that you want returned if the result of logical_test is TRUE. IF(NOT()) - IF(NOT(logical1), value_if_true, )) Use the IF function along with AND, OR and NOT to perform multiple evaluations if conditions are True or False. ![]()
