OK, let's work through this together. We're starting with 164 and we're going to multiply it by 24, which means we add 164 to itself 24 times.
Step 1: 0 + 164 = 164
Step 2: 164 + 164 = 328
Step 3: 328 + 164 = 492
Step 4: 492 + 164 = 656
Step 5: 656 + 164 = 820
Step 6: 820 + 164 = 984
Step 7: 984 + 164 = 1148
Step 8: 1148 + 164 = 1312
Step 9: 1312 + 164 = 1476
Step 10: 1476 + 164 = 1640
Step 11: 1640 + 164 = 1804
Step 12: 1804 + 164 = 1968
Step 13: 1968 + 164 = 2132
Step 14: 2132 + 164 = 2296
Step 15: 2296 + 164 = 2460
Step 16: 2460 + 164 = 2624
Step 17: 2624 + 164 = 2788
Step 18: 2788 + 164 = 2952
Step 19: 2952 + 164 = 3116
Step 20: 3116 + 164 = 3280
Step 21: 3280 + 164 = 3444
Step 22: 3444 + 164 = 3608
Step 23: 3608 + 164 = 3772
Step 24: 3772 + 164 = 3936

So, 164*24 = 3936
