Sure thing! We've got 205 and we're gonna multiply it by 31. That's the same as adding 205 to itself 31 times.
Step 1: 0 + 205 = 205
Step 2: 205 + 205 = 410
Step 3: 410 + 205 = 615
Step 4: 615 + 205 = 820
Step 5: 820 + 205 = 1025
Step 6: 1025 + 205 = 1230
Step 7: 1230 + 205 = 1435
Step 8: 1435 + 205 = 1640
Step 9: 1640 + 205 = 1845
Step 10: 1845 + 205 = 2050
Step 11: 2050 + 205 = 2255
Step 12: 2255 + 205 = 2460
Step 13: 2460 + 205 = 2665
Step 14: 2665 + 205 = 2870
Step 15: 2870 + 205 = 3075
Step 16: 3075 + 205 = 3280
Step 17: 3280 + 205 = 3485
Step 18: 3485 + 205 = 3690
Step 19: 3690 + 205 = 3895
Step 20: 3895 + 205 = 4100
Step 21: 4100 + 205 = 4305
Step 22: 4305 + 205 = 4510
Step 23: 4510 + 205 = 4715
Step 24: 4715 + 205 = 4920
Step 25: 4920 + 205 = 5125
Step 26: 5125 + 205 = 5330
Step 27: 5330 + 205 = 5535
Step 28: 5535 + 205 = 5740
Step 29: 5740 + 205 = 5945
Step 30: 5945 + 205 = 6150
Step 31: 6150 + 205 = 6355

So, 205*31 = 6355
