Alright, let's solve this math problem step by step. First, we have the number 660. Next, we see the multiplication sign, which means we need to multiply something. And what are we multiplying it by? We multiply it by 37. So, we're going to take the number 660 and add it to itself 37 times.
Step 1: 0 + 660 = 660
Step 2: 660 + 660 = 1320
Step 3: 1320 + 660 = 1980
Step 4: 1980 + 660 = 2640
Step 5: 2640 + 660 = 3300
Step 6: 3300 + 660 = 3960
Step 7: 3960 + 660 = 4620
Step 8: 4620 + 660 = 5280
Step 9: 5280 + 660 = 5940
Step 10: 5940 + 660 = 6600
Step 11: 6600 + 660 = 7260
Step 12: 7260 + 660 = 7920
Step 13: 7920 + 660 = 8580
Step 14: 8580 + 660 = 9240
Step 15: 9240 + 660 = 9900
Step 16: 9900 + 660 = 10560
Step 17: 10560 + 660 = 11220
Step 18: 11220 + 660 = 11880
Step 19: 11880 + 660 = 12540
Step 20: 12540 + 660 = 13200
Step 21: 13200 + 660 = 13860
Step 22: 13860 + 660 = 14520
Step 23: 14520 + 660 = 15180
Step 24: 15180 + 660 = 15840
Step 25: 15840 + 660 = 16500
Step 26: 16500 + 660 = 17160
Step 27: 17160 + 660 = 17820
Step 28: 17820 + 660 = 18480
Step 29: 18480 + 660 = 19140
Step 30: 19140 + 660 = 19800
Step 31: 19800 + 660 = 20460
Step 32: 20460 + 660 = 21120
Step 33: 21120 + 660 = 21780
Step 34: 21780 + 660 = 22440
Step 35: 22440 + 660 = 23100
Step 36: 23100 + 660 = 23760
Step 37: 23760 + 660 = 24420

So, 660*37 = 24420
