OK, let's work through this together. We're starting with 136 and we're going to multiply it by 33, which means we add 136 to itself 33 times.
Step 1: 0 + 136 = 136
Step 2: 136 + 136 = 272
Step 3: 272 + 136 = 408
Step 4: 408 + 136 = 544
Step 5: 544 + 136 = 680
Step 6: 680 + 136 = 816
Step 7: 816 + 136 = 952
Step 8: 952 + 136 = 1088
Step 9: 1088 + 136 = 1224
Step 10: 1224 + 136 = 1360
Step 11: 1360 + 136 = 1496
Step 12: 1496 + 136 = 1632
Step 13: 1632 + 136 = 1768
Step 14: 1768 + 136 = 1904
Step 15: 1904 + 136 = 2040
Step 16: 2040 + 136 = 2176
Step 17: 2176 + 136 = 2312
Step 18: 2312 + 136 = 2448
Step 19: 2448 + 136 = 2584
Step 20: 2584 + 136 = 2720
Step 21: 2720 + 136 = 2856
Step 22: 2856 + 136 = 2992
Step 23: 2992 + 136 = 3128
Step 24: 3128 + 136 = 3264
Step 25: 3264 + 136 = 3400
Step 26: 3400 + 136 = 3536
Step 27: 3536 + 136 = 3672
Step 28: 3672 + 136 = 3808
Step 29: 3808 + 136 = 3944
Step 30: 3944 + 136 = 4080
Step 31: 4080 + 136 = 4216
Step 32: 4216 + 136 = 4352
Step 33: 4352 + 136 = 4488

So, 136*33 = 4488
