How to use subscripts

Lily2020

Hello,

This may have been touched on in the explanation videos somewhere but I must have overlooked it or something..

For LR, how do we use subscripts? Some of the explanation videos began using them and they appear useful so I would like to begin implementing it but I am not sure how it works, any clarity would be greatly appreciated.

Here is a link to an example video (question 3): https://7sage.com/lesson/quiz-on-drawing-valid-conclusions-with-translations-2-answers/

Only roses are red. Only thorny things are red. There's a red thing in the flower garden.

Red->Roses
Red->Thorny things
Red (Subscript) Flower Garden ?

Hi! They help to define an element in the group you are working in. In your example above, your group is red and the flower garden is a sub-group of red.

Red --> Roses
Red --> Thorny
Red (sub flower garden)

---

Red (sub flower garden) --> Roses (sub flower garden)
If red things in the flower garden then roses in the flower garden.

Red (sub flower garden) --> Thorny (sub flower garden)
If there are red things in the flower garden then there are thorny things.

Roses some Thorny
Some roses are thorny

Another example would be: All boys like the eat burgers. Tom is a boy. Therefore, Tom likes to eat burgers.

Boy --> Eat Burger
Boy (sub Tom)

---

Eat Burger (sub Tom)

Hope this helps!
