>>17543744yeah and guess what. you can do it backwards too. neat right?
0.2 x 5. which is also the same as 20 % of 5.
you can do 2 x 5.
which is 10. then you go back a digit placement.
1.0. so 1.
0.2 x 0.2
2 x 2 is 4. you just go 2 digits places back
0.04.
its super neat. you can calculate percentages in your head like this.
>>1754374625*48
2 x 4 which is 8. there are 2 0s so 800
2 x 8 which is 16 then u add a 0 so 160
5 x 4 which is 20 then u add a 0 so 200
5 x 8 which is 40
800 + 160 + 200 + 40
1200
yep thats right
