The country's economic crisis was caused in large part because its government had taken on excessive debts.
So at the time the crisis began in earnest, at the end of 2009, its debts as a share of GDP were 127% of GDP or national income - and rose the following year to 146% of GDP.
As a condition of the official rescues, significant public spending cuts and austerity were imposed on Greece. And that had quite an impact on economic activity.
The country was already in recession following the 2008 financial crisis. But since 2010, and
thanks in large part to austerity imposed by Brussels, GDP has shrunk a further 19%.
GDP per head, perhaps a better measure of the hardship imposed on Greeks, has fallen 22% since the onset of the 2008 debacle.
So austerity has certainly hurt.
But has it worked to get Greece's debts down?
To the contrary, Greek debt as a share of GDP has soared to 176% of GDP, as of the end of September 2014.
Now it has fallen a bit in absolute terms. Greek public sector debt was 265bn euros in 2008, 330bn euros in 2010 and was 316bn in September of last year.
But it is debt as a share of GDP or national income which determines affordability. And on that important measure, Greece's debt problem is worse today than it was when it was rescued.
To state the obvious, it is the collapse in the economy which has done the damage. And although Greece started to grow again last year, at the current annual growth rate of 1.6% (which may not be sustained)
it would take longer than a generation to reduce national debt to a manageable level.
