OK, let's work through this together. We're starting with 316 and we're going to multiply it by 31, which means we add 316 to itself 31 times.
Step 1: 0 + 316 = 316
Step 2: 316 + 316 = 632
Step 3: 632 + 316 = 948
Step 4: 948 + 316 = 1264
Step 5: 1264 + 316 = 1580
Step 6: 1580 + 316 = 1896
Step 7: 1896 + 316 = 2212
Step 8: 2212 + 316 = 2528
Step 9: 2528 + 316 = 2844
Step 10: 2844 + 316 = 3160
Step 11: 3160 + 316 = 3476
Step 12: 3476 + 316 = 3792
Step 13: 3792 + 316 = 4108
Step 14: 4108 + 316 = 4424
Step 15: 4424 + 316 = 4740
Step 16: 4740 + 316 = 5056
Step 17: 5056 + 316 = 5372
Step 18: 5372 + 316 = 5688
Step 19: 5688 + 316 = 6004
Step 20: 6004 + 316 = 6320
Step 21: 6320 + 316 = 6636
Step 22: 6636 + 316 = 6952
Step 23: 6952 + 316 = 7268
Step 24: 7268 + 316 = 7584
Step 25: 7584 + 316 = 7900
Step 26: 7900 + 316 = 8216
Step 27: 8216 + 316 = 8532
Step 28: 8532 + 316 = 8848
Step 29: 8848 + 316 = 9164
Step 30: 9164 + 316 = 9480
Step 31: 9480 + 316 = 9796

So, 316*31 = 9796
