What number has 6 zeros?

The digit zero (0) is important for counting large numbers. The larger the number is, the more zeros it has.

Starting at 1,000, large numbers have groups of 0s in them. Every time you jump up to the next level of number, another 0 is added.

The number one thousand has three 0s in it (1,000). The number 10,000 has four 0s in it (10,000). The number one hundred thousand has five 0s in it (100,000). The number one million has six 0s in it (1,000,000).

Every time you have a full group of three zeros, like in one million (1,000,000), you use a comma to separate them.
