The Soroban pt. 2

It was time to see who would be faster at doing some math problems.

I asked one of the other secretaries to write down some arithmetic problems for us to work out. I got a calculator to use, a timer, and she prepared her soroban. When we came up with the answer, we had to write the answer on a piece of paper, and then the person with the correct and fastest answer would be the winner.

The first problem:
1+2+3+4+5+6+7+8+9+10
Winner = SOROBAN
The second problem:
29+22+15+8+1
WINNER = SOROBAN
The third problem:
30+23+16+9+2
WINNER = SOROBAN

I was amazed. She was finished before I was even half way done typing in the numbers. I am thinking that I might have to learn how to use one of those things. Maybe there is an app for that...
