The number line is written from lowest to highest (-∞ to +∞). However, the number before zero is not -1. It's undefined since it's 0.0000000... but not equal to 0.
I'm not sure how you can rationalise a number being before zero also being after zero...it's a contradiction since no numbers on the number line are the same. Also, since 0 is neither negative nor positive (providing the tipping point as it were), then every number that comes before 0 will be negative, and every number that comes after will be positive.
