OK, let's work through this together. We're starting with 267 and we're going to multiply it by 10, which means we add 267 to itself 10 times.
Step 1: 0 + 267 = 267
Step 2: 267 + 267 = 534
Step 3: 534 + 267 = 801
Step 4: 801 + 267 = 1068
Step 5: 1068 + 267 = 1335
Step 6: 1335 + 267 = 1602
Step 7: 1602 + 267 = 1869
Step 8: 1869 + 267 = 2136
Step 9: 2136 + 267 = 2403
Step 10: 2403 + 267 = 2670

So, 267*10 = 2670
