I'll help you test a calculator webpage by following the instructions. Let me start by taking a screenshot to see what's on the screen.

I can see a calculator on the screen. The display currently shows "0". Now I'll follow the first set of instructions: 1. First test: Click 5, then +, then 3, then = and verify the display shows 8. Let me click on 5 first:

Perfect! The display shows "8", which is correct (5 + 3 = 8). The first test passed. Now I'll proceed with the second test: Click 4, then ×, then 2, then = and verify the display shows 8. First, I'll click on 4:
left_click:{'action': 'left_click', 'coordinate': [410, 436]}

I found an issue! The display shows "6" instead of "8". The calculation 4 × 2 should equal 8, but the calculator is showing 6. Let me verify both test results: 1. Test 1: 5 + 3 = 8 ✓ (Correct) 2. Test 2: 4 × 2 = 6 ✗ (Should be 8, but shows 6) Since the second test failed to produce the expected result, I must report this as a FAIL. <answer>FAIL</answer> The calculator failed the second test. When calculating 4 × 2, the expected result was 8, but the calculator displayed 6 instead. This is an incorrect multiplication result, indicating a bug in the calculator's multiplication function.
