Create an unambiguous grammar which generates basic mathematical expressions (using numbers and the four operators +, -, *, /). Without parentheses, parsing and mathematically evaluating expressions created by this string should give the result you'd get while following the order of operations. For now, you may abstract "number" as a single terminal, n. In the order of operations, * and / should be given precedence over + and -. Aside from that, evaluation should occur from left to right. So 8/4*2 would result in 4, not 1.
