Alright, let's solve this math problem step by step. First, we have the number 353. Next, we see the multiplication sign, which means we need to multiply something. And what are we multiplying it by? We multiply it by 31. So, we're going to take the number 353 and add it to itself 31 times.
Step 1: 0 + 353 = 353
Step 2: 353 + 353 = 706
Step 3: 706 + 353 = 1059
Step 4: 1059 + 353 = 1412
Step 5: 1412 + 353 = 1765
Step 6: 1765 + 353 = 2118
Step 7: 2118 + 353 = 2471
Step 8: 2471 + 353 = 2824
Step 9: 2824 + 353 = 3177
Step 10: 3177 + 353 = 3530
Step 11: 3530 + 353 = 3883
Step 12: 3883 + 353 = 4236
Step 13: 4236 + 353 = 4589
Step 14: 4589 + 353 = 4942
Step 15: 4942 + 353 = 5295
Step 16: 5295 + 353 = 5648
Step 17: 5648 + 353 = 6001
Step 18: 6001 + 353 = 6354
Step 19: 6354 + 353 = 6707
Step 20: 6707 + 353 = 7060
Step 21: 7060 + 353 = 7413
Step 22: 7413 + 353 = 7766
Step 23: 7766 + 353 = 8119
Step 24: 8119 + 353 = 8472
Step 25: 8472 + 353 = 8825
Step 26: 8825 + 353 = 9178
Step 27: 9178 + 353 = 9531
Step 28: 9531 + 353 = 9884
Step 29: 9884 + 353 = 10237
Step 30: 10237 + 353 = 10590
Step 31: 10590 + 353 = 10943

So, 353*31 = 10943
