The sum of a number (n) and it's square (n^2) is less than or equal to -3. We have to write this out in math lingo.
"The sum of a number" means addition, aka +. Example: 1+1=2. The sum of 1 and 1 is 2.
n + n^2
Is less than (<) or equal to (=) -3
n + n^2 <= -3
<= on your paper is written with the arrow and a line underneath. That is option J.
