In English
Let us say you have the numeral one (1). You next add a zero adjacent to it. This gives you a number that you call ten. You then add another zero and get hundred. Go on adding more and more zeroes, and you progressively get larger and larger numbers. You get hundred, thousand, ten thousand etc. In this way, with a mere string of zeroes, you can increase the number to million, trillion and so on. You can get astronomical numbers by just adding zeroes to 1. Remove this 1, and you are left with a mere string of zeroes!
