Let's roll up our sleeves and solve this. We have 85 and we're going to multiply it by 29, essentially adding 85 to itself 29 times.
Step 1: 0 + 85 = 85
Step 2: 85 + 85 = 170
Step 3: 170 + 85 = 255
Step 4: 255 + 85 = 340
Step 5: 340 + 85 = 425
Step 6: 425 + 85 = 510
Step 7: 510 + 85 = 595
Step 8: 595 + 85 = 680
Step 9: 680 + 85 = 765
Step 10: 765 + 85 = 850
Step 11: 850 + 85 = 935
Step 12: 935 + 85 = 1020
Step 13: 1020 + 85 = 1105
Step 14: 1105 + 85 = 1190
Step 15: 1190 + 85 = 1275
Step 16: 1275 + 85 = 1360
Step 17: 1360 + 85 = 1445
Step 18: 1445 + 85 = 1530
Step 19: 1530 + 85 = 1615
Step 20: 1615 + 85 = 1700
Step 21: 1700 + 85 = 1785
Step 22: 1785 + 85 = 1870
Step 23: 1870 + 85 = 1955
Step 24: 1955 + 85 = 2040
Step 25: 2040 + 85 = 2125
Step 26: 2125 + 85 = 2210
Step 27: 2210 + 85 = 2295
Step 28: 2295 + 85 = 2380
Step 29: 2380 + 85 = 2465

So, 85*29 = 2465
