OK, let's crack this. We're given 974 and our task is to multiply it by 7. Essentially, we'll be adding 974 to itself 7 times.
Step 1: 0 + 974 = 974
Step 2: 974 + 974 = 1948
Step 3: 1948 + 974 = 2922
Step 4: 2922 + 974 = 3896
Step 5: 3896 + 974 = 4870
Step 6: 4870 + 974 = 5844
Step 7: 5844 + 974 = 6818

So, 974*7 = 6818
