For an equation, you write:
x+2
Where x can represent any number.

Well sum means addition, let the number be x since it is unknown.
So the answer will be x+2

X + 2 would be the sum of a number (X) and 2. X is the placeholder for the number which could be anything.

Let n= a number, "and" means addition, 2 is 2; so your expression would be n+2.

since "a number" can mean ANY number, you would use a variable to represent this value, which could be x, n, y, z... any letter you see fit. x tends to be the standard though.
"sum" means addition, so you want to add the two. therefore you would write:
x+2
"the difference of a number and two" would be similar:
x-2
since "difference" means subtraction

let the number be x
sum means plus
x+2 is your equation
