The Denominator-Split Error

Video not yet published

State

The denominator-split error divides across the terms of a denominator; a/(b + c) is not a/b + a/c.

Show

12/(2 + 4) is 12/6 = 2, but 12/2 + 12/4 is 6 + 3 = 9. The split wrecked the value.

Watch for

A summed denominator is one block; treat it whole.

Builds on

  • Nothing — this is a starting point.

Unlocks

  • Nothing yet depends on this.
