OK, let's crack this. We're given 192 and our task is to multiply it by 24. Essentially, we'll be adding 192 to itself 24 times.
Step 1: 0 + 192 = 192
Step 2: 192 + 192 = 384
Step 3: 384 + 192 = 576
Step 4: 576 + 192 = 768
Step 5: 768 + 192 = 960
Step 6: 960 + 192 = 1152
Step 7: 1152 + 192 = 1344
Step 8: 1344 + 192 = 1536
Step 9: 1536 + 192 = 1728
Step 10: 1728 + 192 = 1920
Step 11: 1920 + 192 = 2112
Step 12: 2112 + 192 = 2304
Step 13: 2304 + 192 = 2496
Step 14: 2496 + 192 = 2688
Step 15: 2688 + 192 = 2880
Step 16: 2880 + 192 = 3072
Step 17: 3072 + 192 = 3264
Step 18: 3264 + 192 = 3456
Step 19: 3456 + 192 = 3648
Step 20: 3648 + 192 = 3840
Step 21: 3840 + 192 = 4032
Step 22: 4032 + 192 = 4224
Step 23: 4224 + 192 = 4416
Step 24: 4416 + 192 = 4608

So, 192*24 = 4608
