Ah okay, thank you so much for that! What a silly mistake I didnt even realize that. And yes, i had actually used grep/map in my code as well to get the same output

@number = qw(1 2 3 4 5 10 11 12 13 14);

@num = map ($_ *$_, (@number)), "\n";
@square = grep ($_ >=100 && $_ <=200, @num);

print "Obtaining square values using map/grep: @square \n";

I just wanted to learn how to do it through a foreach loop. Thanks again for the quick response and help! :)
