Key Concepts
New Concept Comparison problems find the difference between two values. We solve by subtracting the lesser number from the greater or an earlier time from a later one.
Comparison Formula $$ {greater} {lesser} = {difference} $$ $$ g l = d $$.
Elapsed Time Formula $$ {later} {earlier} = {difference} $$ $$ l e = d $$ What’s next This lesson provides the foundation for solving word problems. Soon, you'll apply these formulas to worked examples involving numerical comparisons and elapsed time calculations.
