Math update

hey guys i'm kirsty if you don't know

i have got a way you can work out

the answer in a math test

so this is an example

472 + 527 = ?

so first go in the hundreds column first

400 + 500 = 900

then go in the tens column 

70 + 20 = 90

now go into the ones column

2 + 7 = 9

now you take all the answers are combined them together.

900 + 90 + 9 = 999

so thats how you work it out but only if you need to

here is a another example

123 + 456 = ?

100 + 400 = 500

20 + 50 = 70

3 + 6 = 9

500 + 70 + 9 =579

thats all i have bye bye
