Let's roll up our sleeves and solve this. We have 594 and we're going to multiply it by 16, essentially adding 594 to itself 16 times.
Step 1: 0 + 594 = 594
Step 2: 594 + 594 = 1188
Step 3: 1188 + 594 = 1782
Step 4: 1782 + 594 = 2376
Step 5: 2376 + 594 = 2970
Step 6: 2970 + 594 = 3564
Step 7: 3564 + 594 = 4158
Step 8: 4158 + 594 = 4752
Step 9: 4752 + 594 = 5346
Step 10: 5346 + 594 = 5940
Step 11: 5940 + 594 = 6534
Step 12: 6534 + 594 = 7128
Step 13: 7128 + 594 = 7722
Step 14: 7722 + 594 = 8316
Step 15: 8316 + 594 = 8910
Step 16: 8910 + 594 = 9504

So, 594*16 = 9504
