OK, let's work through this together. We're starting with 186 and we're going to multiply it by 29, which means we add 186 to itself 29 times.
Step 1: 0 + 186 = 186
Step 2: 186 + 186 = 372
Step 3: 372 + 186 = 558
Step 4: 558 + 186 = 744
Step 5: 744 + 186 = 930
Step 6: 930 + 186 = 1116
Step 7: 1116 + 186 = 1302
Step 8: 1302 + 186 = 1488
Step 9: 1488 + 186 = 1674
Step 10: 1674 + 186 = 1860
Step 11: 1860 + 186 = 2046
Step 12: 2046 + 186 = 2232
Step 13: 2232 + 186 = 2418
Step 14: 2418 + 186 = 2604
Step 15: 2604 + 186 = 2790
Step 16: 2790 + 186 = 2976
Step 17: 2976 + 186 = 3162
Step 18: 3162 + 186 = 3348
Step 19: 3348 + 186 = 3534
Step 20: 3534 + 186 = 3720
Step 21: 3720 + 186 = 3906
Step 22: 3906 + 186 = 4092
Step 23: 4092 + 186 = 4278
Step 24: 4278 + 186 = 4464
Step 25: 4464 + 186 = 4650
Step 26: 4650 + 186 = 4836
Step 27: 4836 + 186 = 5022
Step 28: 5022 + 186 = 5208
Step 29: 5208 + 186 = 5394

So, 186*29 = 5394
