Question 511913
To drive 4 blocks north means he is now 4 blocks north of home.
.
When he turns right, he is turning to the east.
By going 6 blocks he is now 6 blocks east of his home and he's still 4 blocks north.
.
When he turns to the south, he is turning to the right.
By going 2 blocks, you subtract 2 blocks from the north position.
So, he is now 6 blocks east and 2 blocks north of home.
.
When he turns right again, he is now going west.
By driving 1 block, you subtract 1 block from the east position.
So, he is now 5 blocks east and 2 blocks north of home.
.
The easiest way is to use graph paper or draw a grid on regular paper and put points at each place he turns.  Then you can use it like a map.
