Barlow question

Last night I was using two scopes. C-90 (1000 fl) with the supplied 2.5 barlow and 18mm eyepiece. (139x?) The other scope is a C-80 refractor (900 fl)with a Meade #140 2x barlow and Apogee zoom eyepiece at about 22mm (81x?). The images were nearly the same size in both. Is my calculator bad? Any ideas? Thanks.
