Let's roll up our sleeves and solve this. We have 419 and we're going to multiply it by 7, essentially adding 419 to itself 7 times.
Step 1: 0 + 419 = 419
Step 2: 419 + 419 = 838
Step 3: 838 + 419 = 1257
Step 4: 1257 + 419 = 1676
Step 5: 1676 + 419 = 2095
Step 6: 2095 + 419 = 2514
Step 7: 2514 + 419 = 2933

So, 419*7 = 2933
