Let's roll up our sleeves and solve this. We have 183 and we're going to multiply it by 7, essentially adding 183 to itself 7 times.
Step 1: 0 + 183 = 183
Step 2: 183 + 183 = 366
Step 3: 366 + 183 = 549
Step 4: 549 + 183 = 732
Step 5: 732 + 183 = 915
Step 6: 915 + 183 = 1098
Step 7: 1098 + 183 = 1281

So, 183*7 = 1281
