Explain how to write and evaluate an algebraic expression.
thirteen less than the quotient of forty and a number; evaluate when n = 2.

40. 40
-13 -13. 20-13. 7
N 2
You would write this this by just looking at the key terms like for example (13 less than) which means it's being subtracted. And (quotient of 40 and a number) means that it's going to be a fraction with 40 at the top and n on the bottom. It's really simple once you get practice hope this helps :)
