Alright, let's solve this math problem step by step. First, we have the number 137. Next, we see the multiplication sign, which means we need to multiply something. And what are we multiplying it by? We multiply it by 33. So, we're going to take the number 137 and add it to itself 33 times.
Step 1: 0 + 137 = 137
Step 2: 137 + 137 = 274
Step 3: 274 + 137 = 411
Step 4: 411 + 137 = 548
Step 5: 548 + 137 = 685
Step 6: 685 + 137 = 822
Step 7: 822 + 137 = 959
Step 8: 959 + 137 = 1096
Step 9: 1096 + 137 = 1233
Step 10: 1233 + 137 = 1370
Step 11: 1370 + 137 = 1507
Step 12: 1507 + 137 = 1644
Step 13: 1644 + 137 = 1781
Step 14: 1781 + 137 = 1918
Step 15: 1918 + 137 = 2055
Step 16: 2055 + 137 = 2192
Step 17: 2192 + 137 = 2329
Step 18: 2329 + 137 = 2466
Step 19: 2466 + 137 = 2603
Step 20: 2603 + 137 = 2740
Step 21: 2740 + 137 = 2877
Step 22: 2877 + 137 = 3014
Step 23: 3014 + 137 = 3151
Step 24: 3151 + 137 = 3288
Step 25: 3288 + 137 = 3425
Step 26: 3425 + 137 = 3562
Step 27: 3562 + 137 = 3699
Step 28: 3699 + 137 = 3836
Step 29: 3836 + 137 = 3973
Step 30: 3973 + 137 = 4110
Step 31: 4110 + 137 = 4247
Step 32: 4247 + 137 = 4384
Step 33: 4384 + 137 = 4521

So, 137*33 = 4521
