OK, let's crack this. We're given 616 and our task is to multiply it by 35. Essentially, we'll be adding 616 to itself 35 times.
Step 1: 0 + 616 = 616
Step 2: 616 + 616 = 1232
Step 3: 1232 + 616 = 1848
Step 4: 1848 + 616 = 2464
Step 5: 2464 + 616 = 3080
Step 6: 3080 + 616 = 3696
Step 7: 3696 + 616 = 4312
Step 8: 4312 + 616 = 4928
Step 9: 4928 + 616 = 5544
Step 10: 5544 + 616 = 6160
Step 11: 6160 + 616 = 6776
Step 12: 6776 + 616 = 7392
Step 13: 7392 + 616 = 8008
Step 14: 8008 + 616 = 8624
Step 15: 8624 + 616 = 9240
Step 16: 9240 + 616 = 9856
Step 17: 9856 + 616 = 10472
Step 18: 10472 + 616 = 11088
Step 19: 11088 + 616 = 11704
Step 20: 11704 + 616 = 12320
Step 21: 12320 + 616 = 12936
Step 22: 12936 + 616 = 13552
Step 23: 13552 + 616 = 14168
Step 24: 14168 + 616 = 14784
Step 25: 14784 + 616 = 15400
Step 26: 15400 + 616 = 16016
Step 27: 16016 + 616 = 16632
Step 28: 16632 + 616 = 17248
Step 29: 17248 + 616 = 17864
Step 30: 17864 + 616 = 18480
Step 31: 18480 + 616 = 19096
Step 32: 19096 + 616 = 19712
Step 33: 19712 + 616 = 20328
Step 34: 20328 + 616 = 20944
Step 35: 20944 + 616 = 21560

So, 616*35 = 21560
