I'm new to Mathematica and 'm going through Mathematica, by Eugene Don.
One of the early problems is to "Compute the sum of 2x+3, 5x+9, and 4x+2.
I enter the following:
(2 x + 3) + (5 x + 9) + (4 x + 2)
When I type "Shift" + "Enter" (I'm on a Mac), I get:
1049242043
What am I doing wrong?
Thanks,
Tony
