OK, let's work through this together. We're starting with 334 and we're going to multiply it by 8, which means we add 334 to itself 8 times.
Step 1: 0 + 334 = 334
Step 2: 334 + 334 = 668
Step 3: 668 + 334 = 1002
Step 4: 1002 + 334 = 1336
Step 5: 1336 + 334 = 1670
Step 6: 1670 + 334 = 2004
Step 7: 2004 + 334 = 2338
Step 8: 2338 + 334 = 2672

So, 334*8 = 2672
