Let b be the universal body of students at a university.
let
s(x) stand for "x is smart".
y(x) stand for "y is young".
c(x) stand for "x is a cs major"
translate the following sentences into quantified formulas.
1- all cs majors are smart
2- some cs majors are smart and not young.
3- no young college students are cs majors.

Step-by-step explanation:

Given that

S(x) stand for "x is smart".

Y(x) stand for "y is young".

C(x) stand for "x is a CS Major"

1) All CS majors are smart :       C(x) ⇒ S(x)

2) Some CS majors are smart and not young.:     There exists a∈C(x) such that a ∉ Y(x)

3) No young college students are CS majors.:   ~Y(s)⇒CS(x)

assuming you mean addition: addition and subtraction are reverse operations.
