The difference between a formal and informal proof in arithmetics is that a formal proof uses equations, whereas an informal proof only uses text. That is option D.

### What is formal and informal proof?

A formal proof is defined as the concept used in arithmetics to show that the final answer to an expression obeys a particular rule of an equation or formula.
An informal proof is defined as the concept that shows the answer to a mathematical expression without the use of formula or derived equation.
Therefore, the difference between the formal and informal proof is that a formal proof uses equations, whereas an informal proof only uses text.
