ANSWER: 6
Here's another example:
Multiply 345 x 320
345
x 3 2 0 multiplier
6900
1 0 3 5__
1 1 0,4 0 0 product
You should know that 0 times any number is 0, but you cannot throw it away if it comes at the
end of a number. If the multiplier ends with one or more zero, you can move the multiplier over to the
right, so that the first figure comes under the first digit of the number to be multiplied. Draw a line,
bring down the 0, and start to multiply from right to left.
2 x 5 = 10
put down 0 under 2 and carry 1
2x4= 8
add I carried and put down 9 under 4
2x3= 6
put down 6 under the 3
3 x 5 = 15
put down 5 under 3 and carry 1
3 x 4 = 12
add 1 carried, put don 3 under 6, and carry 1 again
3x3= 9
add 1 carried and put down 10 to the left of 3
Draw another line and add to get the product,
