You should find the answer to this by looking up the definitions of scalar and vector.
The second sentence doesn't make any sense to me. You will see what I mean when you read those definitions!

I think that the second sentence may be refer to scalar quantities such as temperature, where you can have +10'C but also -10'C.

In a case like this, the signs don't declare the "direction" of the temperature - just its value on a scale with reference to an agreed zero point.
