Let's roll up our sleeves and solve this. We have 326 and we're going to multiply it by 28, essentially adding 326 to itself 28 times.
Step 1: 0 + 326 = 326
Step 2: 326 + 326 = 652
Step 3: 652 + 326 = 978
Step 4: 978 + 326 = 1304
Step 5: 1304 + 326 = 1630
Step 6: 1630 + 326 = 1956
Step 7: 1956 + 326 = 2282
Step 8: 2282 + 326 = 2608
Step 9: 2608 + 326 = 2934
Step 10: 2934 + 326 = 3260
Step 11: 3260 + 326 = 3586
Step 12: 3586 + 326 = 3912
Step 13: 3912 + 326 = 4238
Step 14: 4238 + 326 = 4564
Step 15: 4564 + 326 = 4890
Step 16: 4890 + 326 = 5216
Step 17: 5216 + 326 = 5542
Step 18: 5542 + 326 = 5868
Step 19: 5868 + 326 = 6194
Step 20: 6194 + 326 = 6520
Step 21: 6520 + 326 = 6846
Step 22: 6846 + 326 = 7172
Step 23: 7172 + 326 = 7498
Step 24: 7498 + 326 = 7824
Step 25: 7824 + 326 = 8150
Step 26: 8150 + 326 = 8476
Step 27: 8476 + 326 = 8802
Step 28: 8802 + 326 = 9128

So, 326*28 = 9128
