Alright, let's solve this math problem step by step. First, we have the number 170. 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 170 and add it to itself 28 times.
Step 1: 0 + 170 = 170
Step 2: 170 + 170 = 340
Step 3: 340 + 170 = 510
Step 4: 510 + 170 = 680
Step 5: 680 + 170 = 850
Step 6: 850 + 170 = 1020
Step 7: 1020 + 170 = 1190
Step 8: 1190 + 170 = 1360
Step 9: 1360 + 170 = 1530
Step 10: 1530 + 170 = 1700
Step 11: 1700 + 170 = 1870
Step 12: 1870 + 170 = 2040
Step 13: 2040 + 170 = 2210
Step 14: 2210 + 170 = 2380
Step 15: 2380 + 170 = 2550
Step 16: 2550 + 170 = 2720
Step 17: 2720 + 170 = 2890
Step 18: 2890 + 170 = 3060
Step 19: 3060 + 170 = 3230
Step 20: 3230 + 170 = 3400
Step 21: 3400 + 170 = 3570
Step 22: 3570 + 170 = 3740
Step 23: 3740 + 170 = 3910
Step 24: 3910 + 170 = 4080
Step 25: 4080 + 170 = 4250
Step 26: 4250 + 170 = 4420
Step 27: 4420 + 170 = 4590
Step 28: 4590 + 170 = 4760

So, 170*28 = 4760
