What would happen without zero?
Without zero there would be: No algebra, no arithmetic, no decimal, no accounts, no physical quantity to measure, no boundary between negative and positive numbers and most importantly- no computers!
Why is zero arguably the most important number in all of mathematics?
Zeros importance in maths is due to it position between the negative numbers and positives numbers( -1, 0, 1), as a number itself (0) and as a marker of the absence of other numbers (10).
