When multiplying two digit numbers, with a sum of 10 in their ones digit and with the same tens digit.

Ex. 74 x 76 ( they have the same tens digit which is 7 and their ones digit, when add up, it has a total of 10 )

To multiply it easily, just multiply the ones digit ( 4 x 6 = 24 ,

**24**would be the last two numbers )

then to complete it, just get the number next to the tens digit then multiply to the given original no. ( ex. the tens digit of both numbers is 7, so what's next to 7 is 8 , then multiply both number , 8 x 7 the answer is

**56**. So, to complete

__5624__

More examples:⇒

83 x 87 =

**7221**( 8 x 9 = 72 then 3 x 7 = 21 )

48 x 42 =

**2016 (**4 x 5 = 20 then 8 x 2 = 16 )

68 x 62 =

**4216**( 6 x 7 = 42 then 8 x 2 = 16 )
