Is entering $20,000,000$ the same as entering $20$ million?

Pay careful attention to the instructions given in the problem for how to enter your answer. For example, if a question specifies that you give your answer in millions, you would represent the value $14,000,000$ by entering $14.$ This may be indicated by the units of a header in a table, or alongside the field in a paragraph.
