Stuck on test number 13 for the freeCodeCamp JavaScript Calculator project in the test suite

JavaScript

I am working on the freeCodeCamp JavaScript calculator project and after getting most of the other functionalities properly implemented I’m stuck on test number 13 which basically says that a sequence like “5 * - + 5” = should produce an output of “10” i.e., if 2 or more operators are entered consecutively, the operation performed should be the last operator entered (excluding the negative (-) sign).

I tried different versions of the chooseOperation method Initially this

chooseOperation = (op) => {
    const { previous, current, operation } = this.state;
    if (previous !== "" && current !== "") {
      this.compute();
    }
      this.setState(
        (prevState) => ({
          operation: op,
          previous:
            prevState.current === "" ? prevState.previous : prevState.current,
          current: "",
        })
      );
  };

then this

chooseOperation = (op) => {
    const { previous, current, operation } = this.state;
    if (previous !== "" && current !== "") {
      this.compute();
    }

    if (operation !== "" && op === "-" && previous !== "" && current === "") {
      this.setState((prevState) => ({
        current: `-${prevState.current}`,
        previous: prevState.previous,
        operation: prevState.operation,
      }));
    } else {
      this.setState(
        (prevState) => ({
          operation: op,
          previous:
            prevState.current === "" ? prevState.previous : prevState.current,
          current: "",
        }),
        () => {
          console.log(this.state.operation);
          console.log(previous);
          console.log(current);
        }
      );
    }
  };

and then this

chooseOperation = (op) => {
    const { previous, current, operation } = this.state;
    if (previous !== "" && current !== "") {
      this.compute();
    }

    if (operation !== "" && op === "-" && previous !== "" && current === "") {
      this.setState((prevState) => ({
        current: `-${prevState.current}`,
        previous: prevState.previous,
        operation: prevState.operation,
      }));
    } else if (
      operation !== "" &&
      op !== "-" &&
      previous !== "" &&
      current === "-"
    ) {
      this.setState((prevState) => ({
        current: `${prevState.current}`,
        previous: `${prevState.previous}`,
        operation: op,
      }));
    } else {
      this.setState(
        (prevState) => ({
          operation: op,
          previous:
            prevState.current === "" ? prevState.previous : prevState.current,
          current: "",
        })
      );
    }
  };

none of them worked though,
