State
Cancellation in a fraction removes a factor shared by the whole numerator and the whole denominator; a factor multiplies, a term adds.
Show
In (3x)/(3y), the 3s multiply and cancel to x/y. In (x + 3)/3, the 3 adds — nothing cancels.
Watch for
Divided by itself, an expression is 1; that is the entire license.
Builds on
- Nothing — this is a starting point.
Unlocks
- Nothing yet depends on this.
