I want to convert a mathematics document to pdf, but I am getting missing $ errors.
Here is my code:
\documentclass{article}
\begin{document}
1. All prime numbers are odd
Universal Statement:
For all x \in \mathbb{N} such that for any a,b \in \mathbb{N}
x = ab where a or b must be equal to 1 and for any k \in \mathbb{N}, x = 2k + 1
Counterexample will comprise of:
A counterexample will be an x \in \mathbb{N} such that there exists a k \in \mathbb{N}
such that x = 2k
Counterexample:
2
6. For all real numbers x, we have x^2-2x+2 > 1
Universal Statement:
For all x \in \mathbb{R}, we have x^2-2x+2 > 1
Counterexample will comprise of:
A counterexample will be an x such that x^2-2x+2 < 1
Counterexample:
1
14. For all functions f : \mathbb{R} \rightarrow \mathbb{R}, if f is not increasing,
then it must be decreasing.
Universal Statement:
For all functions f : \mathbb{R} \rightarrow \mathbb{R} for all x_1, x_2 if
x_1 < x_2 and f(x_1) \ngeq f(x_2) then f(x_1) \leq f(x_2)
Counterexample will comprise of:
A counterexample will be a function f such that for all x_1, x_2 if x_1 < x_2 and
f(x_1) \ngeq f(x_2) then f(x_1) \nleq f(x_2)
Counterexample:
None, the statement is true
\end{document}
x \in \mathbb{N}
should be in math mode? so$x \in \mathbb{N}$
and$x^2-2x+2 > 1$
etc
