Formulas
The distance from 2 to 9 is 7
Bigger across number − smaller across number = distance
Assumptions
•
Two points with the same up number are on one line across.
•
The distance is the bigger across number − the smaller one.
•
Numbers to 10, the grid drawn.
Step-by-step
WE KNOW
First point across: 2
Second point across: 9
Up (the same for both): 5
FIND
distance
Step 1 · Find distance
The distance from 2 to 9 is ?
Bigger across number − smaller across number = distance
Count the steps across: the bigger across number minus the smaller one.
Distance = 9 − 2
Distance = 7
Check
Put the numbers back in. Both sides should match.
9 − 2 = 7 ✓
