OK, let's work through this together. We're starting with 414 and we're going to multiply it by 24, which means we add 414 to itself 24 times.
Step 1: 0 + 414 = 414
Step 2: 414 + 414 = 828
Step 3: 828 + 414 = 1242
Step 4: 1242 + 414 = 1656
Step 5: 1656 + 414 = 2070
Step 6: 2070 + 414 = 2484
Step 7: 2484 + 414 = 2898
Step 8: 2898 + 414 = 3312
Step 9: 3312 + 414 = 3726
Step 10: 3726 + 414 = 4140
Step 11: 4140 + 414 = 4554
Step 12: 4554 + 414 = 4968
Step 13: 4968 + 414 = 5382
Step 14: 5382 + 414 = 5796
Step 15: 5796 + 414 = 6210
Step 16: 6210 + 414 = 6624
Step 17: 6624 + 414 = 7038
Step 18: 7038 + 414 = 7452
Step 19: 7452 + 414 = 7866
Step 20: 7866 + 414 = 8280
Step 21: 8280 + 414 = 8694
Step 22: 8694 + 414 = 9108
Step 23: 9108 + 414 = 9522
Step 24: 9522 + 414 = 9936

So, 414*24 = 9936
