You are trying to insert press nails at 3 centimeters (cm) intervals on a paper strip that is 114 centimeters (cm) long. Assuming that you must insert a presser nail at the beginning and end of the paper strip, find out how many presser nails are needed.
114 3 [OP_DIV] 1 [OP_ADD]
var_a = 114
var_b = 3
var_c = var_a / var_b
var_d = 1
var_e = var_c + var_d
print(int(var_e))
