Let's roll up our sleeves and solve this. We have 328 and we're going to multiply it by 7, essentially adding 328 to itself 7 times.
Step 1: 0 + 328 = 328
Step 2: 328 + 328 = 656
Step 3: 656 + 328 = 984
Step 4: 984 + 328 = 1312
Step 5: 1312 + 328 = 1640
Step 6: 1640 + 328 = 1968
Step 7: 1968 + 328 = 2296

So, 328*7 = 2296
