Let's get this math done. We have 558 and we're going to multiply it by 36. This is the same as taking 558 and adding it to itself 36 times.
Step 1: 0 + 558 = 558
Step 2: 558 + 558 = 1116
Step 3: 1116 + 558 = 1674
Step 4: 1674 + 558 = 2232
Step 5: 2232 + 558 = 2790
Step 6: 2790 + 558 = 3348
Step 7: 3348 + 558 = 3906
Step 8: 3906 + 558 = 4464
Step 9: 4464 + 558 = 5022
Step 10: 5022 + 558 = 5580
Step 11: 5580 + 558 = 6138
Step 12: 6138 + 558 = 6696
Step 13: 6696 + 558 = 7254
Step 14: 7254 + 558 = 7812
Step 15: 7812 + 558 = 8370
Step 16: 8370 + 558 = 8928
Step 17: 8928 + 558 = 9486
Step 18: 9486 + 558 = 10044
Step 19: 10044 + 558 = 10602
Step 20: 10602 + 558 = 11160
Step 21: 11160 + 558 = 11718
Step 22: 11718 + 558 = 12276
Step 23: 12276 + 558 = 12834
Step 24: 12834 + 558 = 13392
Step 25: 13392 + 558 = 13950
Step 26: 13950 + 558 = 14508
Step 27: 14508 + 558 = 15066
Step 28: 15066 + 558 = 15624
Step 29: 15624 + 558 = 16182
Step 30: 16182 + 558 = 16740
Step 31: 16740 + 558 = 17298
Step 32: 17298 + 558 = 17856
Step 33: 17856 + 558 = 18414
Step 34: 18414 + 558 = 18972
Step 35: 18972 + 558 = 19530
Step 36: 19530 + 558 = 20088

So, 558*36 = 20088
