Well, when the body of the if-statement is only one command/expression/whatever, you don't necessarily need them because that's part of the syntax. But the body can also have more commands/expressions/etc and then you need them because otherwise, the engine/compiler doesn't know they're all part of the body of the if-statement 
We're doing that @ uni these days so that's why
You can consistently use brackets only when necessary (so not when there's only 1 thing in the if-statement's body) but on the other hand, it's generally better to use them everywhere because you can see at all times what starts and ends where (and, if you wanted to add something else, you'd need to add those brackets again to make sure it functions properly - and, when you forget that, you'd wonder why it's not working right 
)
