OK, let's crack this. We're given 579 and our task is to multiply it by 7. Essentially, we'll be adding 579 to itself 7 times.
Step 1: 0 + 579 = 579
Step 2: 579 + 579 = 1158
Step 3: 1158 + 579 = 1737
Step 4: 1737 + 579 = 2316
Step 5: 2316 + 579 = 2895
Step 6: 2895 + 579 = 3474
Step 7: 3474 + 579 = 4053

So, 579*7 = 4053
