Alright, let's solve this math problem step by step. First, we have the number 756. 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 756 and add it to itself 31 times.
Step 1: 0 + 756 = 756
Step 2: 756 + 756 = 1512
Step 3: 1512 + 756 = 2268
Step 4: 2268 + 756 = 3024
Step 5: 3024 + 756 = 3780
Step 6: 3780 + 756 = 4536
Step 7: 4536 + 756 = 5292
Step 8: 5292 + 756 = 6048
Step 9: 6048 + 756 = 6804
Step 10: 6804 + 756 = 7560
Step 11: 7560 + 756 = 8316
Step 12: 8316 + 756 = 9072
Step 13: 9072 + 756 = 9828
Step 14: 9828 + 756 = 10584
Step 15: 10584 + 756 = 11340
Step 16: 11340 + 756 = 12096
Step 17: 12096 + 756 = 12852
Step 18: 12852 + 756 = 13608
Step 19: 13608 + 756 = 14364
Step 20: 14364 + 756 = 15120
Step 21: 15120 + 756 = 15876
Step 22: 15876 + 756 = 16632
Step 23: 16632 + 756 = 17388
Step 24: 17388 + 756 = 18144
Step 25: 18144 + 756 = 18900
Step 26: 18900 + 756 = 19656
Step 27: 19656 + 756 = 20412
Step 28: 20412 + 756 = 21168
Step 29: 21168 + 756 = 21924
Step 30: 21924 + 756 = 22680
Step 31: 22680 + 756 = 23436

So, 756*31 = 23436
