In A Tour Through Mathematical Logic, Wolf gives the following example in Section 1.3, Quantifiers:
Example 8. The intermediate value theorem states that … $$\forall a, b, f[(a\in\Bbb{R}\wedge b\in\Bbb{R}\wedge a<b\wedge f \text{ is a continuous function from } [a, b] \text{ to } \Bbb{R} \wedge f(a) \cdot f(b) < 0) \rightarrow \exists c (a<c<b \wedge f(c)=0)].$$ So the statement includes eight quantifiers including the ones required to say that $f$ is continuous. Note that seven of the quantifiers involve real number variables, but one of them, $\forall f$, refers to all functions.
How are there seven quantifiers on real number variables? I see only three: two in $\forall a, b$, and one in $\exists c$.
