Let's roll up our sleeves and solve this. We have 226 and we're going to multiply it by 7, essentially adding 226 to itself 7 times.
Step 1: 0 + 226 = 226
Step 2: 226 + 226 = 452
Step 3: 452 + 226 = 678
Step 4: 678 + 226 = 904
Step 5: 904 + 226 = 1130
Step 6: 1130 + 226 = 1356
Step 7: 1356 + 226 = 1582

So, 226*7 = 1582
