when multiplying any number by 10, just add a zero at the end of that number to get your answer. 10*18=180 this rule works for 100, 1000 and other similar numbers. any number multiplied by 100 is that number with 2 zeros after it and any number multiplied by 1000 is that number with 3 zeros.

When a natural number is multiplied by 1,000, the product is

It is a number multiplied by itself multiplied by itself multiplied by itself. So if you start with x, you end up with x*x*x*x.

Well if you remember the rule: Any number times 10 just add a zero at the end. (ex. 2 x 10 = 20) Same rule applies here just with 6 zero's instead of 1 zero. 13,000,000 x 1,000,000 = 13,000,000,000,000 Answer (in words): Thirteen Trillion
