Hi Khaled,

As far as I know, the signs 
	less than: <
	greater than: >
	similar or less than: ⪝
	similar or greater than: ⪞
	less than or equal: ⪬
	greater or equal: ⪭
	(and there are othersigns of the same category)
should be treated in the same way, as with = or \equiv, since they are mathematical relations. On the other hand
	interior product: ⨼
	right hand interior product: ⨽
should be treated as +, \times, or \wedge, since they are binary operations.

Best regards: OK

These signs should have exactly the same spacing around them:
$$a = b$$
$$a \equiv b$$
$$a < b$$
$$a ⪝ b$$
$$a ⪞ b$$
$$a ⪬ b$$
$$a ⪭ b$$
These signs should have exactly the same spacing around them:
$$a ⨼ b$$
$$a ⨽ b$$
$$a \wedge b$$
$$a \times b$$
$$a + b$$
