Translate the following sentences into symbolic form.
a. I sweat if I run or jump.

There are some slightly different sets of symbols people use, so I'd like to see an attempt on your part, or at least some examples you were given. That will also help us see where you need help.

I assume the doubled letters are a result of pasting the problem in, and they are really just p, q, and r.

To start, for (a), I would restate it as "IF I run OR I jump, THEN I sweat". Do you see how to replace the capitalized words with symbols (mostly), and the other words with letters?

rr∨~qq→pp
Is it true?...i don't remember any symbol to write for "If" but the rest is given..kindly tell me if its correct

Yes, this is correct; the lack of a separate symbol for "if" is the reason I said "(mostly)"! The arrow means "if ... then ...".

You're doing well; now try (b).

(But why are the letters still doubled? Is that intentional?)

 

[Hira Javaid]

For part b
~rr∧qq→~pp

 

[Hira Javaid]

Yes they did it intentionally..we have done other examples also with double letters

And Thankyou so much
