Let's roll up our sleeves and solve this. We have 430 and we're going to multiply it by 7, essentially adding 430 to itself 7 times.
Step 1: 0 + 430 = 430
Step 2: 430 + 430 = 860
Step 3: 860 + 430 = 1290
Step 4: 1290 + 430 = 1720
Step 5: 1720 + 430 = 2150
Step 6: 2150 + 430 = 2580
Step 7: 2580 + 430 = 3010

So, 430*7 = 3010
