Sure thing! We've got 404 and we're gonna multiply it by 7. That's the same as adding 404 to itself 7 times.
Step 1: 0 + 404 = 404
Step 2: 404 + 404 = 808
Step 3: 808 + 404 = 1212
Step 4: 1212 + 404 = 1616
Step 5: 1616 + 404 = 2020
Step 6: 2020 + 404 = 2424
Step 7: 2424 + 404 = 2828

So, 404*7 = 2828
