## Subtraction operator " - " - Numeric subtraction

You can use the ** subtraction operator "-" ** to subtract numbers.

my $num3 = $num1-$num2;

This is an example that subtracts 5 from 3.

my $total = 3-5;

In Perl, even a small number of subtractions can be done without being aware of the type.

my $total = 3.5 - 2.7;
