let m_i>0 represent total imports from country i, and let x_i>0 represent total exports [from country i]
imports from china(i)exports from china(i)mi = imports from china (small number) (143) xi = exports from china (big number) (439)YOU said
(exports - imports) / imports = (438947.4 - 143545.7) / 438947.4 = ~0.673
Just admit it already, you divided by the wrong number (exports instead of imports). Imports is the larger number, thus deficit. How many more walls of text are you gonna post about your math error?
