1.1.4   Say whether the following expressions and signs are true or false:
   •    a2+b2= c2 a plus b is equal c
   •    p>q; p is greater than q
   •    a ≠ b ; a does not equal b; or: a is not equal to b; or: a is not b
   •    F(x)= 0 f of x(is) identical with zero
   •    a ≥ b a (is) greater than or equals b
   •    a ≈ b ; a approximately equals b,
   •    1, 2, 3, …one, two, three and so on infinity
