Show me the man (or woman) above mistakes?

Kemi Adeosun, the Hon. Minister of Finance, according to Wikipedia, commenced her career as an Accounting assistant at British Telecom Company, London, from 1989 till 1990 after which she moved to Goodman Jones, London, working as a Senior audit officer from 1990 till 1993. 

She became Manager of Internal Audit at London Underground Limited, London and Prism Consulting from 1994 till 2000 before joining Price Waterhouse Coopers, London as Senior Manager from 2000 till 2002. 

In 2002, Kemi became financial controller at Chapel Hill Denham Management and subsequently, Managing Director in 2010. After working with Quo Vadis Partnership as Managing Director in 2010 and 2011, she was appointed the Commissioner of Finance in Ogun State, from 2011 till 2015.

And so, with such a professional pedigree, if she says 16+6=24, it certainly was a slip, which any smart accountant even from Mars can make. 

If that was the only thing the Wailing Wailers could take out of the Minister's briefing, then too bad. They should go take a chill-pill for all I care.

No amount of negative campaigns by sore losers can distract PMB's government from the mission to rescue Nigeria after 6 years of the invasion of the locusts.
