OK, let's work through this together. We're starting with 877 and we're going to multiply it by 32, which means we add 877 to itself 32 times.
Step 1: 0 + 877 = 877
Step 2: 877 + 877 = 1754
Step 3: 1754 + 877 = 2631
Step 4: 2631 + 877 = 3508
Step 5: 3508 + 877 = 4385
Step 6: 4385 + 877 = 5262
Step 7: 5262 + 877 = 6139
Step 8: 6139 + 877 = 7016
Step 9: 7016 + 877 = 7893
Step 10: 7893 + 877 = 8770
Step 11: 8770 + 877 = 9647
Step 12: 9647 + 877 = 10524
Step 13: 10524 + 877 = 11401
Step 14: 11401 + 877 = 12278
Step 15: 12278 + 877 = 13155
Step 16: 13155 + 877 = 14032
Step 17: 14032 + 877 = 14909
Step 18: 14909 + 877 = 15786
Step 19: 15786 + 877 = 16663
Step 20: 16663 + 877 = 17540
Step 21: 17540 + 877 = 18417
Step 22: 18417 + 877 = 19294
Step 23: 19294 + 877 = 20171
Step 24: 20171 + 877 = 21048
Step 25: 21048 + 877 = 21925
Step 26: 21925 + 877 = 22802
Step 27: 22802 + 877 = 23679
Step 28: 23679 + 877 = 24556
Step 29: 24556 + 877 = 25433
Step 30: 25433 + 877 = 26310
Step 31: 26310 + 877 = 27187
Step 32: 27187 + 877 = 28064

So, 877*32 = 28064
