OK, let's work through this together. We're starting with 971 and we're going to multiply it by 7, which means we add 971 to itself 7 times.
Step 1: 0 + 971 = 971
Step 2: 971 + 971 = 1942
Step 3: 1942 + 971 = 2913
Step 4: 2913 + 971 = 3884
Step 5: 3884 + 971 = 4855
Step 6: 4855 + 971 = 5826
Step 7: 5826 + 971 = 6797

So, 971*7 = 6797
