Question: 20 trillion how many zeros?
Answer: One million is a 7 figure number with six zeros. So 1,000,000 x 1,000,000 = 1,000,000,000,000 which is 1 trillion with 12 zeros. So 20 trillion is 20 * 1,000,000,000,000 = 20,000,000,000,000 You can count the zeros to be sure but it will be 20 followed by 12 zeros, for a total of 13 zeros in 20 Trillion.
