OK, let's work through this together. We're starting with 434 and we're going to multiply it by 7, which means we add 434 to itself 7 times.
Step 1: 0 + 434 = 434
Step 2: 434 + 434 = 868
Step 3: 868 + 434 = 1302
Step 4: 1302 + 434 = 1736
Step 5: 1736 + 434 = 2170
Step 6: 2170 + 434 = 2604
Step 7: 2604 + 434 = 3038

So, 434*7 = 3038
