What gives, J? Explain.

The last sentence illustrates the behaviour in the absence of parentheses: in effect, the
sentence is [evaluated from right to left] or, equivalently, the [right argument of each verb is
the value of the entire phrase to its right].

8-3+4 [3+4 = 7] [4+3 = 7] [4+3 - 8 = 1]
8-3-3-3 [3-3-3-8 = 5] [3-3=0 0-3=-3 -3-8=5] What gives??? [8-3 -(3-3)]
[3-3-3-8+] [-3 -3 -3 +8 = -1]  What gives??? that's odd.
[+3 -3 -3 +8 = 5] Properly reversed. [+8 -3 -3 -3] [3- 3- 3- 8+] I still find it odd.
