Chapter 4: Quiz 2: $expr. Wrong solution?

[Lisa_N_A]

I am talking about this question.

Shouldn’t the second answer be wrong?

$lt is not the opposite of $gt as the solution states:

$let would be correct, right? However as statet $lt should be wrong…

I think the quiz is correct.

a > b is equivalent to b < a while a >= b is equivalent to b <= a

Which translate to

{ $gt : [ a , b ] } being equivalent to { $lt : [ b , a ] }
while { $gte : [ a , b ] } being equivalent to { $lte : [ b , a ] }

Yes, I think you are right Thank you!
