1) a) 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 precendence over and -. Aside from that, evaluation should occur from left to right. So 8/42 would result in 4, not 1. 1 23 would be 7. 4 35-6/24 would be 4 15-6/2*4
