Order of Operations · Challenge problem

Zoe's calculator ignores the order of operations and always works from RIGHT to LEFT: it does the last operation first, then the one before it, and so on. She types 60÷5×4−2+160 \div 5 \times 4 - 2 + 1. How much larger is the correct value than the number her calculator shows?
