Maths

kia everyone today I will be explaining 1 easy way that I know to solve maths question so put your pjs on and pull out some popcorn and some drinks and sit tight and let's go.


1) 21x14=
so the first thing you do is switch the number so you switch the 4 and 1 but you have to make the 1 into a 11 so it won't have 1 you will have 11. After so put them on the opposite side. then you end up having to add 4 and 21.

4+21=25
then add the 0 to it which is...
250
then you times the switch up numbers so...
4x11=44

then you add up...
250+44=294

so the is one way to do but if you know one comment down low so you can teach me while I teach you.
