@PicturesFoIder In my brain, I see right away that the 2 and 4 is 6, plus 1 because the 7 and 8 will be more than 10. Then I see that 8 is just 2 less than 10, so I just take 2 from 7 to give 75.
@lilkabob1@PicturesFoIder This is sort of how I do it, except I first notice that the 4 plus 2 will be 6 plus one more, then because 8 is 2 from 10, that means 2 will come off the 7 for 75
