Let's roll up our sleeves and solve this. We have 946 and we're going to multiply it by 13, essentially adding 946 to itself 13 times.
Step 1: 0 + 946 = 946
Step 2: 946 + 946 = 1892
Step 3: 1892 + 946 = 2838
Step 4: 2838 + 946 = 3784
Step 5: 3784 + 946 = 4730
Step 6: 4730 + 946 = 5676
Step 7: 5676 + 946 = 6622
Step 8: 6622 + 946 = 7568
Step 9: 7568 + 946 = 8514
Step 10: 8514 + 946 = 9460
Step 11: 9460 + 946 = 10406
Step 12: 10406 + 946 = 11352
Step 13: 11352 + 946 = 12298

So, 946*13 = 12298
