OK, let's work through this together. We're starting with 650 and we're going to multiply it by 8, which means we add 650 to itself 8 times.
Step 1: 0 + 650 = 650
Step 2: 650 + 650 = 1300
Step 3: 1300 + 650 = 1950
Step 4: 1950 + 650 = 2600
Step 5: 2600 + 650 = 3250
Step 6: 3250 + 650 = 3900
Step 7: 3900 + 650 = 4550
Step 8: 4550 + 650 = 5200

So, 650*8 = 5200
