Earlier quoted context omitted.
It’s surprisingly simple, actually. A cricket pitch is a long strip. Bowler bowls from one end, batter strikes the bowl from the other. Scoring is done by running from one end of that strip to the other (the unit of scoring is literally called a run). Six legal bowls make an over. There are two batters in play at each point in time, one at each end of the pitch, and they both must run towards the other end of the pit…
So the batter runs towards the bowler? 102 runs? Can a run score more than one? What was the down by 6 thing? It's not really that simple?
They can run more than one (get to the other side, turn around, run back, etc) but the chance of the wicket you're running to being hit with the ball (so you're out) becomes larger so they usually manage 1, sometimes 2 or even 3. And both batters have to run the same amount.
If the number of runs is even, they end up on the same side as they started from.
