Today you will be learning another amazing shortcut way of multiplying any 2 numbers.This trick is especially effective to use when the number in between the 2 numbers to be multiplied is 5.You will see why...... Let us go through the steps Step 1:Identify the number in between the 2 numbers. Step 2:Find the square of the number identified in step 1. Step 3:Subtract 1 from the result obtained in step 2. Let us now consider few examples to understand better Example 1:12 x 14=? Notice that there is difference of 2 between the numbers 12 and 14. We shall now apply the trick that we learnt Step 1:We find that 13 lies in between 12 and 14. Step 2:Squaring 13 we get 13^{2}=169 Step 3:Subtracting 1 from the result obtained in step 2 We get 169 1=168 Ans 12 x 14=168 Example 2:24 x 26=?Step 1:We find that 25 lies in between 24 and 26.Step 2:Squaring 25 we get 25^{2}=625 (Use the shortcut trick to square any number ending in 5) Step 3:Subtracting 1 from the result obtained in step 2 We get 625 1=624 Ans 24 x 26=624
