Let's roll up our sleeves and solve this. We have 632 and we're going to multiply it by 7, essentially adding 632 to itself 7 times.
Step 1: 0 + 632 = 632
Step 2: 632 + 632 = 1264
Step 3: 1264 + 632 = 1896
Step 4: 1896 + 632 = 2528
Step 5: 2528 + 632 = 3160
Step 6: 3160 + 632 = 3792
Step 7: 3792 + 632 = 4424

So, 632*7 = 4424
