Let's roll up our sleeves and solve this. We have 268 and we're going to multiply it by 7, essentially adding 268 to itself 7 times.
Step 1: 0 + 268 = 268
Step 2: 268 + 268 = 536
Step 3: 536 + 268 = 804
Step 4: 804 + 268 = 1072
Step 5: 1072 + 268 = 1340
Step 6: 1340 + 268 = 1608
Step 7: 1608 + 268 = 1876

So, 268*7 = 1876
