Multiplication methods

Multiplying  Multiplication is mainly taught in three ways - the grid method, Chinese multiplication and traditional column method.  The Grid Method involves breaking the number up into hundreds, tens, units etc. Multiplying them together and then adding the answers. E.g. : 34 x 65 Break the 34 into 30 and 4, 30 4 similarly break 65 into 60 and 5 60 5

Next….. …. multiply the numbers together ( e.g. 30 x 60 = 1800) 3 x 6 = 18, then add 2 zeros 30 4 60 1800 240 5 150 20 finally add the answers 1 8 0 0 2 4 0 1 5 0 1 1 2 0 2 2 1 0

Chinese multiplication is set out similarly to the grid method but it has the bonus of never having to multiply numbers higher than 9x9. 34 6 5 E.g. 34 x 65 Multiply the numbers together, placing the tens above the diagonal line and units underneath. 34 6 1 8 1 5 2 0 4 5 2

Next….. …... add together the numbers on the diagonals. 6 1 8 1 5 2 0 4 5 2 34 0 2 1 1 2 1 So, 34 x 65 = 2210

Or the more traditional column method can be used First multiply the 34 by 5 3 4 x 6 5 1 7 0 Then multiply the 34 by 60, this can be done by adding a 0 and multiplying by 6 3 4 x 6 5 1 7 0 2 0 4 0 Finally add the two answers 3 4 x 6 5 1 7 0 +2 0 4 0 2 2 1 0
