If you find it difficult to deal with decimal multiplication, temporarily use the following short cut, but in the long run definitely understand, learn and practice decimal multiplication.

Temporary trick:

Given 3.5 x 4

Now multiply 3.5 by 10 (but remember that you did this)

So now the product is 35 x 4 = 140 (remember you multiplied 3.5 by 10)

So now the product is 140 but you have to divide this by 10 to nullify the effect of you having multiplied 3.5 by 10 previously. So divide 140 by 10 which is easy

140/10 = 14.0 or simply 14
