Alright, let's solve this math problem step by step. First, we have the number 824. Next, we see the multiplication sign, which means we need to multiply something. And what are we multiplying it by? We multiply it by 28. So, we're going to take the number 824 and add it to itself 28 times.
Step 1: 0 + 824 = 824
Step 2: 824 + 824 = 1648
Step 3: 1648 + 824 = 2472
Step 4: 2472 + 824 = 3296
Step 5: 3296 + 824 = 4120
Step 6: 4120 + 824 = 4944
Step 7: 4944 + 824 = 5768
Step 8: 5768 + 824 = 6592
Step 9: 6592 + 824 = 7416
Step 10: 7416 + 824 = 8240
Step 11: 8240 + 824 = 9064
Step 12: 9064 + 824 = 9888
Step 13: 9888 + 824 = 10712
Step 14: 10712 + 824 = 11536
Step 15: 11536 + 824 = 12360
Step 16: 12360 + 824 = 13184
Step 17: 13184 + 824 = 14008
Step 18: 14008 + 824 = 14832
Step 19: 14832 + 824 = 15656
Step 20: 15656 + 824 = 16480
Step 21: 16480 + 824 = 17304
Step 22: 17304 + 824 = 18128
Step 23: 18128 + 824 = 18952
Step 24: 18952 + 824 = 19776
Step 25: 19776 + 824 = 20600
Step 26: 20600 + 824 = 21424
Step 27: 21424 + 824 = 22248
Step 28: 22248 + 824 = 23072

So, 824*28 = 23072
