4 quarters make one. ¼+¼+¼+¼=1. Also four quarters make a dollar: 25¢ + 25¢ + 25¢ + 25¢ = $1.00
5 x 5 = 25... 25 + 5 = 30.... 30 / 5 = 6.

4 fives of 25 = (4*5)*25 = 20*25 = 500
One way to use four fours to make 25 is 4 + 4 + 4 + √4, which equals 25.
Well, 25 twos is equal to 50. So 10 fives are equal equal to 25 twos.
125 / 5 = 25
