Let's roll up our sleeves and solve this. We have 176 and we're going to multiply it by 20, essentially adding 176 to itself 20 times.
Step 1: 0 + 176 = 176
Step 2: 176 + 176 = 352
Step 3: 352 + 176 = 528
Step 4: 528 + 176 = 704
Step 5: 704 + 176 = 880
Step 6: 880 + 176 = 1056
Step 7: 1056 + 176 = 1232
Step 8: 1232 + 176 = 1408
Step 9: 1408 + 176 = 1584
Step 10: 1584 + 176 = 1760
Step 11: 1760 + 176 = 1936
Step 12: 1936 + 176 = 2112
Step 13: 2112 + 176 = 2288
Step 14: 2288 + 176 = 2464
Step 15: 2464 + 176 = 2640
Step 16: 2640 + 176 = 2816
Step 17: 2816 + 176 = 2992
Step 18: 2992 + 176 = 3168
Step 19: 3168 + 176 = 3344
Step 20: 3344 + 176 = 3520

So, 176*20 = 3520
