/*Single-statement if statements
*the if statements here only run one statement, so they
*don't need braces ("{}"). Multi-statement if statements
*look like:
*
	if(condition){

	}

*you can always use a multi-statement if statement in place
*of a single-statement if statement, but never the other way
*around.
