Common Mistakes in Math Proofs

Directly solve the equation without simplification

Tease apart the factorials to simplify the problem

Use a calculator to find the factorial values

Ignore the factorials and focus on the variables

Skipping the limit evaluation

Aligning terms to pair numerators and denominators

Ignoring the denominators

Using a calculator for complex calculations

Using a calculator for proofs

Using the wrong formula

Not stating where assumptions were used

Skipping the entire proof

Use a greater than sign regardless of context

Ignore the inequalities

Use a less than sign when appropriate

Always use an equal sign

It equals zero

It equals one

It equals e

It equals infinity

Skipping the integration entirely

Ignoring the partial fractions

Using the wrong substitution

Forgetting the reverse chain rule

It simplifies the problem

It is optional and can be ignored

It makes the problem more complex

It is only a suggestion

Ignore the reading time

Calmly review the questions

Focus on the diagram

Skip to the hardest question

Solving complex equations

Identifying parallel lines

Understanding the diagram

Calculating factorials

It is a random number

It is irrelevant to limits

It is always equal to zero

It is the result of a famous limit
