    sir, I noticed another very interesting thing in (1) the answer is 20,8-3=5 (2) the answer is 40 10-6=4 5 is one larger than 4 and is half in the answer
    my prediction
    ————–
    number-the number of which decomposition we’re talking about(8-3=5)
    if it’s 6 the answer will be 10 and so on
    if it’s 3 the answer will be 80 and so on
    🙂 🙂 🙂 🙂 🙂

  • Student 18

    We can think of it like first, we take the number we want to start the decomposing with say 6 and then we subtract 6 out of 10, that is 4 and then we have all the possibilities of 4, so there are 8 possibilities of decomposing 10 starting with 6

  • Student 3

    8=3+5
    5 can be written in 16 ways

    10=6+4
    4 can be written in 8 ways
    This is what I found
