Alright, let's solve this math problem step by step. First, we have the number 856. Next, we see the multiplication sign, which means we need to multiply something. And what are we multiplying it by? We multiply it by 27. So, we're going to take the number 856 and add it to itself 27 times.
Step 1: 0 + 856 = 856
Step 2: 856 + 856 = 1712
Step 3: 1712 + 856 = 2568
Step 4: 2568 + 856 = 3424
Step 5: 3424 + 856 = 4280
Step 6: 4280 + 856 = 5136
Step 7: 5136 + 856 = 5992
Step 8: 5992 + 856 = 6848
Step 9: 6848 + 856 = 7704
Step 10: 7704 + 856 = 8560
Step 11: 8560 + 856 = 9416
Step 12: 9416 + 856 = 10272
Step 13: 10272 + 856 = 11128
Step 14: 11128 + 856 = 11984
Step 15: 11984 + 856 = 12840
Step 16: 12840 + 856 = 13696
Step 17: 13696 + 856 = 14552
Step 18: 14552 + 856 = 15408
Step 19: 15408 + 856 = 16264
Step 20: 16264 + 856 = 17120
Step 21: 17120 + 856 = 17976
Step 22: 17976 + 856 = 18832
Step 23: 18832 + 856 = 19688
Step 24: 19688 + 856 = 20544
Step 25: 20544 + 856 = 21400
Step 26: 21400 + 856 = 22256
Step 27: 22256 + 856 = 23112

So, 856*27 = 23112
