OK, let's work through this together. We're starting with 806 and we're going to multiply it by 9, which means we add 806 to itself 9 times.
Step 1: 0 + 806 = 806
Step 2: 806 + 806 = 1612
Step 3: 1612 + 806 = 2418
Step 4: 2418 + 806 = 3224
Step 5: 3224 + 806 = 4030
Step 6: 4030 + 806 = 4836
Step 7: 4836 + 806 = 5642
Step 8: 5642 + 806 = 6448
Step 9: 6448 + 806 = 7254

So, 806*9 = 7254
