OK, let's work through this together. We're starting with 830 and we're going to multiply it by 7, which means we add 830 to itself 7 times.
Step 1: 0 + 830 = 830
Step 2: 830 + 830 = 1660
Step 3: 1660 + 830 = 2490
Step 4: 2490 + 830 = 3320
Step 5: 3320 + 830 = 4150
Step 6: 4150 + 830 = 4980
Step 7: 4980 + 830 = 5810

So, 830*7 = 5810
