School A has 217 boys and School B has 196 girls. If the sum of the number of male students in school A and the number of male students in school B is equal to the total number of female students in school A and school B, what is the difference between the number of male students in school B and the number of female students in school A?
217 196 [OP_SUB] [OP_ABS]
var_a = 217
var_b = 196
var_c = var_a - var_b
var_d = abs(var_c)
print(int(var_d))
