Alright, let's solve this math problem step by step. First, we have the number 550. Next, we see the multiplication sign, which means we need to multiply something. And what are we multiplying it by? We multiply it by 23. So, we're going to take the number 550 and add it to itself 23 times.
Step 1: 0 + 550 = 550
Step 2: 550 + 550 = 1100
Step 3: 1100 + 550 = 1650
Step 4: 1650 + 550 = 2200
Step 5: 2200 + 550 = 2750
Step 6: 2750 + 550 = 3300
Step 7: 3300 + 550 = 3850
Step 8: 3850 + 550 = 4400
Step 9: 4400 + 550 = 4950
Step 10: 4950 + 550 = 5500
Step 11: 5500 + 550 = 6050
Step 12: 6050 + 550 = 6600
Step 13: 6600 + 550 = 7150
Step 14: 7150 + 550 = 7700
Step 15: 7700 + 550 = 8250
Step 16: 8250 + 550 = 8800
Step 17: 8800 + 550 = 9350
Step 18: 9350 + 550 = 9900
Step 19: 9900 + 550 = 10450
Step 20: 10450 + 550 = 11000
Step 21: 11000 + 550 = 11550
Step 22: 11550 + 550 = 12100
Step 23: 12100 + 550 = 12650

So, 550*23 = 12650
