OK, let's crack this. We're given 550 and our task is to multiply it by 26. Essentially, we'll be adding 550 to itself 26 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
Step 24: 12650 + 550 = 13200
Step 25: 13200 + 550 = 13750
Step 26: 13750 + 550 = 14300

So, 550*26 = 14300
