f(f(1)) = f(1 + 7) = f(8) = 8 + 7 = 15

Why does 3+5=8 help you find 8-5
Nat2105 [25]

Answer:

Step-by-step explanation:

let me see if I can explain this...

3 + 5 = 8....those 2 numbers added together equals the total(8)...if u take the total(8) and subtract one of the numbers, it gives u the other number.

8 - 5 = 3 and 8 - 3 = 5

here's another one...

30 + 60 = 100

100 - 30 = 60 and 100 - 60 = 30
