Let's roll up our sleeves and solve this. We have 253 and we're going to multiply it by 11, essentially adding 253 to itself 11 times.
Step 1: 0 + 253 = 253
Step 2: 253 + 253 = 506
Step 3: 506 + 253 = 759
Step 4: 759 + 253 = 1012
Step 5: 1012 + 253 = 1265
Step 6: 1265 + 253 = 1518
Step 7: 1518 + 253 = 1771
Step 8: 1771 + 253 = 2024
Step 9: 2024 + 253 = 2277
Step 10: 2277 + 253 = 2530
Step 11: 2530 + 253 = 2783

So, 253*11 = 2783
