How to compare numbers but allowing a tolerance in Excel?

doc compare numbers with tolerance 1

In Excel, we can apply the formula: =A1=B1 to return a TRUE or FALSE to identify if the two compared cells are equal, but, sometimes, we need to compare two numbers but allowing a tolerance. For example, I have the following data, column A and column B, to compare them with a plus or minus tolerance of 5, that is to say if cell A1 is more or less than cell B1 5 number, it will get a TRUE, otherwise, get a FALSE as following screenshot shown. To solve this problem, this article may help you.
