5 x 1000000000 = 5000000000
300000 + 5000000000 = 5000300000
It is 5000000000.
5000000000/ 250000000=20!
5000000000 add 100000000000000000000000000000000000 = 99999999999999996863366107917975552
91000000 divided into 5000000000 = 0.0182
500 billion times 10 is 5000000000

How about: 15 times 15 = 225
11 times 225/11 = 225 (20.45454545... repeating)
15 times 15 equals 225.
5 times 45 = 225
