Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

Math question: decrease one number by increasing another

Sorry if my question is quite silly, but my math imagination isn't my best skill. I want to increase number when another is decreasing. I mean one float will increase its value while another will be decreasing. I don't have idea how to do that :) I've started experimenting with negative values and addition but I need positive value at the end.

Can some one help me with this? Thanks.

Where's the problem?

You have a third variable (possibly const) containing the amount by which to change both other values. Then you subtract it from one value and add it to another.
