**ISSUE DETECTED!** The display shows "6" but it should show "8" (since 4 × 2 = 8). This is a failure - the calculator is not calculating the multiplication correctly. <answer>FAIL</answer> The calculator fails Task 2. When performing the calculation 4 × 2 = , the display shows "6" instead of the correct result "8". Task 1 (5 + 3 = 8) worked correctly, but Task 2 (4 × 2 = 8) returned an incorrect result of 6.
