Why is my sum outputting a curly bracket?

I'm trying to output even numbers 2-200 in one single line of code, but instead of displaying the number it's displaying a curly bracket after the text.

Here's the code:

    disp(['Sum of even numbers from 2 to 200 =',sum(2:2:200)])

You are attempting to combine strings and numeric data. That will not work.

Try this:

disp(['Sum of even numbers from 2 to 200 =',num2str(sum(2:2:200))])

The best option is likely sprintf or fprintf.

num2str(sum(2:2:200))

I recommend to use

fprintf('Sum of even numbers from 2 to 200: %d',sum(2:2:200))

Or

"Sum of even numbers from 2 to 200: "+sum(2:2:200)

are you trying output the sum of even numbers 2-200 (i.e. 10100)? Try:

disp(['Sum of even numbers from 2 to 200 =',num2str(sum(2:2:200))])

otherwise MATLAB converts 10100 to unicode, which is a curly bracket
