Let's roll up our sleeves and solve this. We have 134 and we're going to multiply it by 28, essentially adding 134 to itself 28 times.
Step 1: 0 + 134 = 134
Step 2: 134 + 134 = 268
Step 3: 268 + 134 = 402
Step 4: 402 + 134 = 536
Step 5: 536 + 134 = 670
Step 6: 670 + 134 = 804
Step 7: 804 + 134 = 938
Step 8: 938 + 134 = 1072
Step 9: 1072 + 134 = 1206
Step 10: 1206 + 134 = 1340
Step 11: 1340 + 134 = 1474
Step 12: 1474 + 134 = 1608
Step 13: 1608 + 134 = 1742
Step 14: 1742 + 134 = 1876
Step 15: 1876 + 134 = 2010
Step 16: 2010 + 134 = 2144
Step 17: 2144 + 134 = 2278
Step 18: 2278 + 134 = 2412
Step 19: 2412 + 134 = 2546
Step 20: 2546 + 134 = 2680
Step 21: 2680 + 134 = 2814
Step 22: 2814 + 134 = 2948
Step 23: 2948 + 134 = 3082
Step 24: 3082 + 134 = 3216
Step 25: 3216 + 134 = 3350
Step 26: 3350 + 134 = 3484
Step 27: 3484 + 134 = 3618
Step 28: 3618 + 134 = 3752

So, 134*28 = 3752
