Obama was the 44th president but before trump was elected there has only been 43 true or false?

This is true. There have been only 43 presidents, but Grover Cleveland is counted twice because he was elected as the 22nd and the 24th president and they were not together in years but at different times. So that is why there are 44 presidents counted.
Fun fact: Only 12 of the 43 presidents have been elected for two terms and have served for the full two terms.
