Let's get this math done. We have 110 and we're going to multiply it by 39. This is the same as taking 110 and adding it to itself 39 times.
Step 1: 0 + 110 = 110
Step 2: 110 + 110 = 220
Step 3: 220 + 110 = 330
Step 4: 330 + 110 = 440
Step 5: 440 + 110 = 550
Step 6: 550 + 110 = 660
Step 7: 660 + 110 = 770
Step 8: 770 + 110 = 880
Step 9: 880 + 110 = 990
Step 10: 990 + 110 = 1100
Step 11: 1100 + 110 = 1210
Step 12: 1210 + 110 = 1320
Step 13: 1320 + 110 = 1430
Step 14: 1430 + 110 = 1540
Step 15: 1540 + 110 = 1650
Step 16: 1650 + 110 = 1760
Step 17: 1760 + 110 = 1870
Step 18: 1870 + 110 = 1980
Step 19: 1980 + 110 = 2090
Step 20: 2090 + 110 = 2200
Step 21: 2200 + 110 = 2310
Step 22: 2310 + 110 = 2420
Step 23: 2420 + 110 = 2530
Step 24: 2530 + 110 = 2640
Step 25: 2640 + 110 = 2750
Step 26: 2750 + 110 = 2860
Step 27: 2860 + 110 = 2970
Step 28: 2970 + 110 = 3080
Step 29: 3080 + 110 = 3190
Step 30: 3190 + 110 = 3300
Step 31: 3300 + 110 = 3410
Step 32: 3410 + 110 = 3520
Step 33: 3520 + 110 = 3630
Step 34: 3630 + 110 = 3740
Step 35: 3740 + 110 = 3850
Step 36: 3850 + 110 = 3960
Step 37: 3960 + 110 = 4070
Step 38: 4070 + 110 = 4180
Step 39: 4180 + 110 = 4290

So, 110*39 = 4290
