4 different concepts I can think of.
Take away: I had 8 and lost 3. 8-3 is 5
Comparison: Joe has 8 and I have 3. How many more does Joe have 8-3 is 5
Distance (this one is my favorite): Joe is 8 miles east of the house. I am 3 miles east. What is the distance between us? 8-3 is 5
Missing amount. I have 3 and I need 8. How many more do I need 8-3 is 5
