Operators

Unary, Binary, and Ternary operators refer to how many terms an operator is applied to, not how many characters are in the operator (e.g., === is not a ternary operator, but rather a binary comparison operator, since it is applied to only two terms, $a === $b).

that was my understanding as well.

unary operators have one operand such as a++ (a is the operand)

binary operators have two operands such as a + b (a and b are operands)

ternary operators have three operands such as a > b ? true : false. (a > b, true, and false are operands)

what do you think Hampton Paulk ?

Stone is exactly right. This video is misleading and should be edited to correct the multiple mistakes in it.

BTW, WTG on your 25k Treehouse points, Stone. You da man!

If Stone is right, I am very confused, why Treehouse is not doing anything to this misslead by Hampton Paulk!
