Sure thing, let's get straight to it. We start with 33 and we're going to multiply it by 15, which means adding 33 to itself 15 times.
Step 1: 0 + 33 = 33
Step 2: 33 + 33 = 66
Step 3: 66 + 33 = 99
Step 4: 99 + 33 = 132
Step 5: 132 + 33 = 165
Step 6: 165 + 33 = 198
Step 7: 198 + 33 = 231
Step 8: 231 + 33 = 264
Step 9: 264 + 33 = 297
Step 10: 297 + 33 = 330
Step 11: 330 + 33 = 363
Step 12: 363 + 33 = 396
Step 13: 396 + 33 = 429
Step 14: 429 + 33 = 462
Step 15: 462 + 33 = 495

So, 33*15 = 495
