Let's get this math done. We have 632 and we're going to multiply it by 31. This is the same as taking 632 and adding it to itself 31 times.
Step 1: 0 + 632 = 632
Step 2: 632 + 632 = 1264
Step 3: 1264 + 632 = 1896
Step 4: 1896 + 632 = 2528
Step 5: 2528 + 632 = 3160
Step 6: 3160 + 632 = 3792
Step 7: 3792 + 632 = 4424
Step 8: 4424 + 632 = 5056
Step 9: 5056 + 632 = 5688
Step 10: 5688 + 632 = 6320
Step 11: 6320 + 632 = 6952
Step 12: 6952 + 632 = 7584
Step 13: 7584 + 632 = 8216
Step 14: 8216 + 632 = 8848
Step 15: 8848 + 632 = 9480
Step 16: 9480 + 632 = 10112
Step 17: 10112 + 632 = 10744
Step 18: 10744 + 632 = 11376
Step 19: 11376 + 632 = 12008
Step 20: 12008 + 632 = 12640
Step 21: 12640 + 632 = 13272
Step 22: 13272 + 632 = 13904
Step 23: 13904 + 632 = 14536
Step 24: 14536 + 632 = 15168
Step 25: 15168 + 632 = 15800
Step 26: 15800 + 632 = 16432
Step 27: 16432 + 632 = 17064
Step 28: 17064 + 632 = 17696
Step 29: 17696 + 632 = 18328
Step 30: 18328 + 632 = 18960
Step 31: 18960 + 632 = 19592

So, 632*31 = 19592
