Let's roll up our sleeves and solve this. We have 524 and we're going to multiply it by 18, essentially adding 524 to itself 18 times.
Step 1: 0 + 524 = 524
Step 2: 524 + 524 = 1048
Step 3: 1048 + 524 = 1572
Step 4: 1572 + 524 = 2096
Step 5: 2096 + 524 = 2620
Step 6: 2620 + 524 = 3144
Step 7: 3144 + 524 = 3668
Step 8: 3668 + 524 = 4192
Step 9: 4192 + 524 = 4716
Step 10: 4716 + 524 = 5240
Step 11: 5240 + 524 = 5764
Step 12: 5764 + 524 = 6288
Step 13: 6288 + 524 = 6812
Step 14: 6812 + 524 = 7336
Step 15: 7336 + 524 = 7860
Step 16: 7860 + 524 = 8384
Step 17: 8384 + 524 = 8908
Step 18: 8908 + 524 = 9432

So, 524*18 = 9432
