Without delay, let's solve this. We've got 659 and we will be multiplying it by 28, that is, adding 659 to itself 28 times.
Step 1: 0 + 659 = 659
Step 2: 659 + 659 = 1318
Step 3: 1318 + 659 = 1977
Step 4: 1977 + 659 = 2636
Step 5: 2636 + 659 = 3295
Step 6: 3295 + 659 = 3954
Step 7: 3954 + 659 = 4613
Step 8: 4613 + 659 = 5272
Step 9: 5272 + 659 = 5931
Step 10: 5931 + 659 = 6590
Step 11: 6590 + 659 = 7249
Step 12: 7249 + 659 = 7908
Step 13: 7908 + 659 = 8567
Step 14: 8567 + 659 = 9226
Step 15: 9226 + 659 = 9885
Step 16: 9885 + 659 = 10544
Step 17: 10544 + 659 = 11203
Step 18: 11203 + 659 = 11862
Step 19: 11862 + 659 = 12521
Step 20: 12521 + 659 = 13180
Step 21: 13180 + 659 = 13839
Step 22: 13839 + 659 = 14498
Step 23: 14498 + 659 = 15157
Step 24: 15157 + 659 = 15816
Step 25: 15816 + 659 = 16475
Step 26: 16475 + 659 = 17134
Step 27: 17134 + 659 = 17793
Step 28: 17793 + 659 = 18452

So, 659*28 = 18452
