Minyoung's 5th graders have 30 students in class (a), 27 students in class (b), and 28 students in class (c). I'm going to give out 4 notebooks to every 5th grader. If there are 400 notebooks, find how many notebooks would be left after giving them to all 5th graders.
400 30 27 [OP_ADD] 28 [OP_ADD] 4 [OP_MUL] [OP_SUB]
var_a = 400
var_b = 30
var_c = 27
var_d = var_b + var_c
var_e = 28
var_f = var_d + var_e
var_g = 4
var_h = var_f * var_g
var_i = var_a - var_h
print(int(var_i))
