OK, let's work through this together. We're starting with 412 and we're going to multiply it by 7, which means we add 412 to itself 7 times.
Step 1: 0 + 412 = 412
Step 2: 412 + 412 = 824
Step 3: 824 + 412 = 1236
Step 4: 1236 + 412 = 1648
Step 5: 1648 + 412 = 2060
Step 6: 2060 + 412 = 2472
Step 7: 2472 + 412 = 2884

So, 412*7 = 2884
