1,07x65 + 1,07x26 + 1,07x9

= 1,07(65+26+9)

= 1,07x100 = 107

Great, but on my Android phone the X 9 is missing.

There are three original terms being added together, each signifying a certain number of 1.07's.

In total, there are 65 + 26 + 9 ⇒ 80 + 11 + 9 ⇒ 100 1.07's, so the expression becomes 1.07 × 100 ⇒ 107.
