Chapter 105 How many are there in total?
There are seven cats in each of the seven houses; any one of the seven cats can catch seven mice; and each of the seven mice will eat seven ears of wheat ; If every ear of wheat can peel off seven grains of wheat, may I ask: How many houses, cats, mice, ears of wheat, and grains of wheat should be added together?
房子有7间，猫有72=49只，鼠有73=343只，麦穗有74=2401个，麦粒有75=16807合。全部加起来是7 72 73 74 75=19607.
[Answer: The total is 19607.]
