Order of operations applies even without parentheses

The Order of Operations convention applies even without parentheses! This is a common myth in mathematics where some think you blindly solve left to right without parentheses.

Please review the order of operations convention that you were taught in school, but you forgot.

You can not even explain the formula for the area of a circle without understanding the order of operations.

1) Parentheses (none here)
2) exponents ( the radius squared)
3) multiplication (pi times radius squared)
4) addition and subtraction (none here)
