OK, let's work through this together. We're starting with 910 and we're going to multiply it by 6, which means we add 910 to itself 6 times.
Step 1: 0 + 910 = 910
Step 2: 910 + 910 = 1820
Step 3: 1820 + 910 = 2730
Step 4: 2730 + 910 = 3640
Step 5: 3640 + 910 = 4550
Step 6: 4550 + 910 = 5460

So, 910*6 = 5460
