This table shows the interactive router modes used in PCB design software with their descriptions.

Formula

COUNTIF(A2:A5, "*")

This formula counts all non-empty cells in the range A2 to A5, which represent the listed router modes.

Step-by-Step Trace

Step	Expression	Evaluates To	Explanation
1	COUNTIF(A2:A5, "*")	4	Counts all non-empty cells in A2 to A5, which are 4 modes.

The formula returns 4, the total number of interactive router modes listed.

A 5

B 3

C 4

D 2

Key Result

COUNTIF with "*" counts all non-empty cells in a range, useful to count listed items like router modes.

Transcript

We have a list of interactive router modes in cells A2 to A5. The formula COUNTIF(A2:A5, "*") counts how many modes are listed by counting all non-empty cells in that range. Since all four cells contain mode names, the formula returns 4. This helps quickly know how many modes are available without manually counting.
