Lady Nanazin's Test

The reason for Alexander's test was of course obvious.

Without calculators and only the most basic abacus, most businesses relied on mental math to get their daily transactions. 

It would be too tedious to get a pen and paper for simple problems like 27 minus 14. 

But naturally, they had to be also accurate, not just fast.

A fact that was all the more true for a business like banks. Alexander did not dare imagine the kind of shenanigans that would unfold if the tellers and cashiers started to make basic arithmetic mistakes.

Hence he had decided to test their boss first, presenting her with quite a difficult problem. 

And indeed, this little test was much harder than it might seem on paper. 

Because remember Alexander did not say anything in the beginning. 

There were no instructions on whether to add, subtract, or multiply… heck there were no clues that he was even taking a test.

He had just started speaking out of the blue.
