Hi
The Max and Min are straightforward
=MAX($A$1:$H$1) 18
=MIN($A$1:$H$1) -23

for the Min positive, the array formula
{=MIN(IF($A$1:$H$10,$A$1:$H$1))} 3
for the Max negative
{=MAX(IF($A$1:$H$1<0,$A$1:$H$1))} -9

For array formulae, commit or Edit using Control+Shift+Enter (CSE) not
just Enter.
Do not type the curly braces { } yourself, if you use CSE, Excel will
insert them for you.
