Math question (GST)

[Super Ninja]

Can you really calculate your GST by doing:

E.g 115 x 3 / 23 = 15

Can you really calculate it like that, it just seems so easy :3

Just do it step by step
Am too lazy for paper
1. 115 x 3 = 345
2 . 345 / 23 = 15
And yeah it's pretty funny how me and u are doing same work xd
