* * * is (1+32) * 32/2 = 33 *16 = 528 (g)
Both sides are equal, that is, 528/2 = 264 (grams)
So, if we make up 264 grams, the rest is naturally 264, that is, we have reached a balance.
Simply calculate, 1 to 20g all add up (1+20) * 20/2 = 2 10 (grams), which is not enough for 264g.
2 10+2 1+22+23=276
276-264= 12
That is to say, from 1 to 23g, if12g is removed, it is exactly 264g. Put it aside. Balance the rest on the other side.
Check, (1+23) * 23/2-12 =12 * 23-12 = 276-12 = 264.
Ok.
Of course, the easiest way is to add 1+32, 2+3 1 ... from beginning to end, you get another set of 33 grams and another set of *** 16.
At this time, as long as you ensure that there are 8 groups on both sides, you will definitely balance.
