Understand the rule first
Mark each move from the current position. Keep horizontal and vertical displacement separately, and update facing direction immediately after every turn.
Track direction, distance and final position through a sequence of movements.
Mark each move from the current position. Keep horizontal and vertical displacement separately, and update facing direction immediately after every turn.
Applying every movement from the original position or forgetting that a turn changes later directions.
Reusable method: Mark each position rather than calculating only at the end.Combine horizontal moves separately from vertical moves.
Answer A: 2 right and 2 up

Quick method: Mark each position rather than calculating only at the end.
Change the column twice and the row once.
Answer C: C2
A1 → C1 after two east, then C2 after one north.
Quick method: Mark each position rather than calculating only at the end.
Track each facing direction before moving.
Answer D: 3 east and 6 north
It moves 4 north, 3 east, then 2 more north: 3 east and 6 north.
Quick method: Mark each position rather than calculating only at the end.
Reverse both original directions.
Answer A: 2 east and 3 north
The reverse of west is east and the reverse of south is north.
Quick method: Mark each position rather than calculating only at the end.
Combine north and south movement.
Answer A: 2 east and 2 north
Five north minus three south leaves two north, together with two east.
Quick method: Mark each position rather than calculating only at the end.
Imagine facing left on a compass and turning towards the bottom.
Answer B: south
A left turn from west faces south.
Quick method: Mark each position rather than calculating only at the end.
Move D → C → B, then add three to the row.
Answer C: B7
Two west reaches B and three north changes 4 to 7, giving B7.
Quick method: Mark each position rather than calculating only at the end.
