Verifizierte Beispielex = 5; x += 3; x → 8 AddTo[5, 1] → AddTo::rvalue: 5 is not a variable with a value, so its value cannot be changed. 5 += 1 AppendTo[{1, 2}, 3] → AppendTo::rvalue: {1, 2} is not a variable with a value, so its value cannot be changed. AppendTo[{1, 2}, 3]AppendTo[q, 3] → AppendTo::rvalue: q is not a variable with a value, so its value cannot be changed. AppendTo[q, 3]k = {{1}, {2}}; AppendTo[k[[1]], 9] → {1, 9}m = {1, 2}; AppendTo[m[[1]], 9] → AppendTo::normal: Nonatomic expression expected at position 1 in AppendTo[m[[1]], 9]. AppendTo[m[[1]], 9]5 += 1 → AddTo::rvalue: 5 is not a variable with a value, so its value cannot be changed. 5 += 1 a = 5; 2 a++ → 10 a = 5; a++ 2 → 10 1++2 → Increment::rvalue: 1 is not a variable with a value, so its value cannot be changed. 2*1++1 + +2 → 3
