Arithmetic Subtraction Operator

The arithmetic subtraction (-) operator returns the difference between two numeric operands.

If the first operand is a number, but the second is a string or a Boolean, the second operand is converted to a number.

Examples:

1 - 2
Result = -1

1 - "JUAN"
Result = 1

100 - "32JUAN"
Result = 68
