Sure thing, let's get straight to it. We start with 170 and we're going to multiply it by 27, which means adding 170 to itself 27 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

So, 170*27 = 4590
