In english:
- $\bigl(x+y^2\bigr)$ is ('x' plus 'y' squared)
- $(x+y)^2$ is ('x' plus 'y' squared)
How can I make the difference in english between the two?
In english:
To completely eliminate all confusion, many people will use "$x$ plus $y$-squared" for the first, and "$x$ plus $y$ quantity squared" for the second one.
