Dear Faraidun,

           There are more than 300 mathematical journals indexed in Thomson Reuters. Majority of them are free of processing charges. You can find very high impact factors and low ones as well. 

For example:

http://www.worldscientific.com/page/m3as/aims-scope

http://www.springer.com/mathematics/computational+science+%26+engineering/journal/10543

http://www.journals.elsevier.com/advances-in-applied-mathematics/

Dear Mr. Ahmed

can you tell me, which one free to publication, when will be submit it ?

I saw some of them is high price!

with regards

Dear Faraidun,

            Which impact factor you are expecting? like 1, higher or lower? I guess all the journals I listed are free with the open access option. You don't need to choose open access option then you will have the free processing fees by default.

Best of luck

Thank you again Dear Mr. Ahmed

the impact factor does not matter, just I want  the journal in Thomson Router, with free to publish the paper

with my regards for you 

So you can consider one of these according to the IF:
