Alright, let's solve this math problem step by step. First, we have the number 755. 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 755 and add it to itself 31 times.
Step 1: 0 + 755 = 755
Step 2: 755 + 755 = 1510
Step 3: 1510 + 755 = 2265
Step 4: 2265 + 755 = 3020
Step 5: 3020 + 755 = 3775
Step 6: 3775 + 755 = 4530
Step 7: 4530 + 755 = 5285
Step 8: 5285 + 755 = 6040
Step 9: 6040 + 755 = 6795
Step 10: 6795 + 755 = 7550
Step 11: 7550 + 755 = 8305
Step 12: 8305 + 755 = 9060
Step 13: 9060 + 755 = 9815
Step 14: 9815 + 755 = 10570
Step 15: 10570 + 755 = 11325
Step 16: 11325 + 755 = 12080
Step 17: 12080 + 755 = 12835
Step 18: 12835 + 755 = 13590
Step 19: 13590 + 755 = 14345
Step 20: 14345 + 755 = 15100
Step 21: 15100 + 755 = 15855
Step 22: 15855 + 755 = 16610
Step 23: 16610 + 755 = 17365
Step 24: 17365 + 755 = 18120
Step 25: 18120 + 755 = 18875
Step 26: 18875 + 755 = 19630
Step 27: 19630 + 755 = 20385
Step 28: 20385 + 755 = 21140
Step 29: 21140 + 755 = 21895
Step 30: 21895 + 755 = 22650
Step 31: 22650 + 755 = 23405

So, 755*31 = 23405
