Implicit Intersection describes a formula behavior in Excel where many values are reduced to a single value.
In other words, entering a formula with control + shift + enter disables implicit intersection.
For example, if same formula above is entered in cell D9, the result is #VALUE.
This makes it possible to create formulas that manipulate multiple values input as ranges.
This @ symbol is called the implicit intersection operator, and itdisablesarray behavior.
In other words, it tells Excel you want asinglevalue.
This behavior only occurs in dynamic array versions of Excel.
