Math Problem Statement

Write an equation only using Four fours that equals 77 (44= two fours)

Solution

To create an equation using only four 4's that equals 77, you can use the following expression:

444+44=77\frac{44}{4} + 44 = 77

Here's the breakdown:

  1. 4444 is considered as two fours combined.
  2. 444=11\frac{44}{4} = 11.
  3. Adding another 44 gives 11+44=7711 + 44 = 77.
