Station 7

Let’s do an addition problem.

Let’s compute $251 + 124$.

Such a problem is usually set up this way.

This addition problem is easy to compute:

$2+1$ is $3$;

$5+2$ is $7$;

and $1+4$ is $5$.

The answer $375$ appears.

You can try it too on the $1\leftarrow 10$ machine.

Now try this problem with machine.

Go ahead, do some explosions in the machine to get an answer to $358+287$ you think society would accept.

Write down, or say out loud, the straightforward answer to the sum. Then run the machine and adjust that answer to one that won’t sound weird to society.

Let's go to the next station!
