Sure thing! We've got 431 and we're gonna multiply it by 36. That's the same as adding 431 to itself 36 times.
Step 1: 0 + 431 = 431
Step 2: 431 + 431 = 862
Step 3: 862 + 431 = 1293
Step 4: 1293 + 431 = 1724
Step 5: 1724 + 431 = 2155
Step 6: 2155 + 431 = 2586
Step 7: 2586 + 431 = 3017
Step 8: 3017 + 431 = 3448
Step 9: 3448 + 431 = 3879
Step 10: 3879 + 431 = 4310
Step 11: 4310 + 431 = 4741
Step 12: 4741 + 431 = 5172
Step 13: 5172 + 431 = 5603
Step 14: 5603 + 431 = 6034
Step 15: 6034 + 431 = 6465
Step 16: 6465 + 431 = 6896
Step 17: 6896 + 431 = 7327
Step 18: 7327 + 431 = 7758
Step 19: 7758 + 431 = 8189
Step 20: 8189 + 431 = 8620
Step 21: 8620 + 431 = 9051
Step 22: 9051 + 431 = 9482
Step 23: 9482 + 431 = 9913
Step 24: 9913 + 431 = 10344
Step 25: 10344 + 431 = 10775
Step 26: 10775 + 431 = 11206
Step 27: 11206 + 431 = 11637
Step 28: 11637 + 431 = 12068
Step 29: 12068 + 431 = 12499
Step 30: 12499 + 431 = 12930
Step 31: 12930 + 431 = 13361
Step 32: 13361 + 431 = 13792
Step 33: 13792 + 431 = 14223
Step 34: 14223 + 431 = 14654
Step 35: 14654 + 431 = 15085
Step 36: 15085 + 431 = 15516

So, 431*36 = 15516
