Multiply up to 20 x 20 in your Head

when I want to show you is have to

easily multiply
up to 20 times 20 in your head you can

use this
for multiplying numbers from 11 up to

nineteen
so let's say
we want to multiply 15 times 13 you take

the large in number
and in your hands he plays it
on top of the other one so now
you cross out the botnet number you're

just using
the remaining three numbers
for the next steps
so now you take \$15 plus 3 this
equals 18
you take the eighteen in at 20 behind it
so you get 180 now
you're gonna multiply 5
times 3 510
sweeney equals 15 and now what you doing

yes
you take the 100 eighty and at 15 to it
what you're gonna get is 195
cell 15 times 13 equals
195 its net easy
so would I would suggest is you practice

this on paper a few times
to get used to it thank you for watching
