What is the estimated number?

Estimation is the process of finding the number which is close enough to the exact solution. But it is not an exact answer.

So the first part must have the answer of times 2.

Then decide how many zeroes must be added. By simple math if you do 118,000,000,000 * 20.

Then you get 2,360,000,000,000.
