Boolean Math

[Art]

I have three cells with formulas that return a boolean value.
I need a formula in the fourth cell that returns True only if the first
three cells are all True.

 

[David Biddulph]

=AND(A1,B1,C1)

 

[Pete_UK]

Try this:

=AND(A1,A2,A3)

Hope this helps.

Hi there.
The following formula returns true only if A1, A2 and A3 are all TRUE:

=and(A1,A2,A3)

Regards,
Otávio

Assuming your cells are D58 you could use this:
=IF(COUNTIF(D57,"true")=3,TRUE,FALSE)

Hope that helps,

You don't need =IF(...,TRUE,FALSE)
Your formula is the same as =COUNTIF(D57,"true")=3 or
=COUNTIF(D57,TRUE)=3
but AND is easier.

AND another

=A1*B1*C1=1

 

[Bernard Liengme]

or even
=A1*B1*C1<>0
SORRY!

AND another

=A1*B1*C1=1

 

[Rick Rothstein]

This slightly shorter AND method seems to work also (assuming the cells are
contiguous)...

=AND(A1:C1)

or

=AND(A1:A3)
