Let's get this math done. We have 780 and we're going to multiply it by 44. This is the same as taking 780 and adding it to itself 44 times.
Step 1: 0 + 780 = 780
Step 2: 780 + 780 = 1560
Step 3: 1560 + 780 = 2340
Step 4: 2340 + 780 = 3120
Step 5: 3120 + 780 = 3900
Step 6: 3900 + 780 = 4680
Step 7: 4680 + 780 = 5460
Step 8: 5460 + 780 = 6240
Step 9: 6240 + 780 = 7020
Step 10: 7020 + 780 = 7800
Step 11: 7800 + 780 = 8580
Step 12: 8580 + 780 = 9360
Step 13: 9360 + 780 = 10140
Step 14: 10140 + 780 = 10920
Step 15: 10920 + 780 = 11700
Step 16: 11700 + 780 = 12480
Step 17: 12480 + 780 = 13260
Step 18: 13260 + 780 = 14040
Step 19: 14040 + 780 = 14820
Step 20: 14820 + 780 = 15600
Step 21: 15600 + 780 = 16380
Step 22: 16380 + 780 = 17160
Step 23: 17160 + 780 = 17940
Step 24: 17940 + 780 = 18720
Step 25: 18720 + 780 = 19500
Step 26: 19500 + 780 = 20280
Step 27: 20280 + 780 = 21060
Step 28: 21060 + 780 = 21840
Step 29: 21840 + 780 = 22620
Step 30: 22620 + 780 = 23400
Step 31: 23400 + 780 = 24180
Step 32: 24180 + 780 = 24960
Step 33: 24960 + 780 = 25740
Step 34: 25740 + 780 = 26520
Step 35: 26520 + 780 = 27300
Step 36: 27300 + 780 = 28080
Step 37: 28080 + 780 = 28860
Step 38: 28860 + 780 = 29640
Step 39: 29640 + 780 = 30420
Step 40: 30420 + 780 = 31200
Step 41: 31200 + 780 = 31980
Step 42: 31980 + 780 = 32760
Step 43: 32760 + 780 = 33540
Step 44: 33540 + 780 = 34320

So, 780*44 = 34320
