Question

Transcribed Image Text:You are given the following information about a
new binary operator valid for a,b,c E R+, known as smiley-face:
I. In order of operations, it takes precedence over Multiplicaiton/Divison.
That is, the order of operations is now: P,E,Ⓒ,MD,AS
II. aa = a
III. aⒸ (boc)
√(ab).c
Note that THIS smiley-face operator is actuall self consistent. To wit:
Using the definition: a (aa)
√(aa).a
√a·a
Evaluating the parentheses first: a (aⒸa) = a Ⓒa = a
That is to say: I BELIEVE it is self-consistent!
Let me know if I've messed up again!!!
