OK, let's work through this together. We're starting with 202 and we're going to multiply it by 31, which means we add 202 to itself 31 times.
Step 1: 0 + 202 = 202
Step 2: 202 + 202 = 404
Step 3: 404 + 202 = 606
Step 4: 606 + 202 = 808
Step 5: 808 + 202 = 1010
Step 6: 1010 + 202 = 1212
Step 7: 1212 + 202 = 1414
Step 8: 1414 + 202 = 1616
Step 9: 1616 + 202 = 1818
Step 10: 1818 + 202 = 2020
Step 11: 2020 + 202 = 2222
Step 12: 2222 + 202 = 2424
Step 13: 2424 + 202 = 2626
Step 14: 2626 + 202 = 2828
Step 15: 2828 + 202 = 3030
Step 16: 3030 + 202 = 3232
Step 17: 3232 + 202 = 3434
Step 18: 3434 + 202 = 3636
Step 19: 3636 + 202 = 3838
Step 20: 3838 + 202 = 4040
Step 21: 4040 + 202 = 4242
Step 22: 4242 + 202 = 4444
Step 23: 4444 + 202 = 4646
Step 24: 4646 + 202 = 4848
Step 25: 4848 + 202 = 5050
Step 26: 5050 + 202 = 5252
Step 27: 5252 + 202 = 5454
Step 28: 5454 + 202 = 5656
Step 29: 5656 + 202 = 5858
Step 30: 5858 + 202 = 6060
Step 31: 6060 + 202 = 6262

So, 202*31 = 6262
