In this problem, we're being asked to multiply 156 times 328.
00:04
Well, to do this, i'm going to set this problem up vertically.
00:07
So i'm going to have 156 times 328.
00:11
So first thing we're going to do is multiply the number in the one's place, the 8, by 156.
00:17
So 8 times 6 is 48, so we bring down the 8 and carry the 4.
00:22
Next, we have 8 times 5, which is 40, plus 4, which is 44.
00:26
So i bring down the 4 and carry the 4.
00:29
Now we multiply 8 times 1, which is 8, plus 4, which is 12.
00:34
Now i'm going to cross off those 4s that i carried.
00:38
And in the next row, i'm going to start with 0 for a placeholder, because i'm now multiplying by the digit in the 10's place.
00:45
And now we just do our multiplication.
00:46
Well, 2 times 9 is 12.
00:49
Or sorry, that's 2 times 6.
00:51
2 times 6 is 12, so i bring down the 2 and carry the 1.
00:55
And then we multiply 2 times 5, which is 10, plus 1, which is 11.
00:59
So i bring down the 1 and carry the 1...
