RE: Little explorations with HP calculators (no Prime)
Another little problem that may be solved with a calculator, although the idea is that you try before without.
we have the numbers: 1 2 3 4 5 6 7 8 and we multiply those adjacent to one another, getting: 1x2 2x3 3x4 etc... 2 6 12 20 30 42 56 notice that now we have 7 numbers, not 8. then we continue in this way until we have only one number. Is this number smaller than 10^80 ? if possible use spoilers as usual Code:
